Denial of Service Attacks
On Tuesday, March 11th, GitHub was largely unreachable for roughly 2 hours as the result of an evolving distributed denial of service (DDoS) attack. I know that you rely on GitHub to be available all the time, and I'm sorry we let you down. I'd like to explain what happened, how we responded to it, and what we're doing to reduce the impact of future attacks like this.
Over the last year, we have seen a large number and variety of denial of service attacks against various parts of the GitHub infrastructure. There are two broad types of attack that we think about when we're building our mitigation strategy: volumetric and complex.
We have designed our DDoS mitigation capabilities to allow us to respond to both volumetric and complex attacks.
Volumetric attacks are intended to exhaust some resource through the sheer weight of the attack. This type of attack has been seen with increasing frequency lately through UDP based amplification attacks using protocols like DNS, SNMP, or NTP. The only way to withstand an attack like this is to have more available network capacity than the sum of all of the attacking nodes or to filter the attack traffic before it reaches your network.
Dealing with volumetric attacks is a game of numbers. Whoever has more capacity wins. With that in mind, we have taken a few steps to allow us to defend against these types of attacks.
We operate our external network connections at very low utilization. Our internet transit circuits are able to handle almost an order of magnitude more traffic than our normal daily peak. We also continually evaluate opportunities to expand our network capacity. This helps to give us some headroom for larger attacks, especially since they tend to ramp up over a period of time to their ultimate peak throughput.
In addition to managing the capacity of our own network, we've contracted with a leading DDoS mitigation service provider. A simple Hubot command can reroute our traffic to their network which can handle terabits per second. They're able to absorb the attack, filter out the malicious traffic, and forward the legitimate traffic on to us for normal processing.
Complex attacks are also designed to exhaust resources, but generally by performing expensive operations rather than saturating a network connection. Examples of these are things like SSL negotiation attacks, requests against computationally intensive parts of web applications, and the "Slowloris" attack. These kinds of attacks often require significant understanding of the application architecture to mitigate, so we prefer to handle them ourselves. This allows us to make the best decisions when choosing countermeasures and tuning them to minimize the impact on legitimate traffic.
First, we devote significant engineering effort to hardening all parts of our computing infrastructure. This involves things like tuning Linux network buffer sizes, configuring load balancers with appropriate timeouts, applying rate limiting within our application tier, and so on. Building resilience into our infrastructure is a core engineering value for us that requires continuous iteration and improvement.
We've also purchased and installed a software and hardware platform for detecting and mitigating complex DDoS attacks. This allows us to perform detailed inspection of our traffic so that we can apply traffic filtering and access control rules to block attack traffic. Having operational control of the platform allows us to very quickly adjust our countermeasures to deal with evolving attacks.
Our DDoS mitigation partner is also able to assist with these types of attacks, and we use them as a final line of defense.
So what happened?
At 21:25 UTC we began investigating reports of connectivity problems to github.com. We opened an incident on our status site at 21:29 UTC to let customers know we were aware of the problem and working to resolve it.
As we began investigating we noticed an apparent backlog of connections at our load balancing tier. When we see this, it typically corresponds with a performance problem with some part of our backend applications.
After some investigation, we discovered that we were seeing several thousand HTTP requests per second distributed across thousands of IP addresses for a crafted URL. These requests were being sent to the non-SSL HTTP port and were then being redirected to HTTPS, which was consuming capacity in our load balancers and in our application tier. Unfortunately, we did not have a pre-configured way to block these requests and it took us a while to deploy a change to block them.
By 22:35 UTC we had blocked the malicious request and the site appeared to be operating normally.
Despite the fact that things appeared to be stabilizing, we were still seeing a very high number of SSL connections on our load balancers. After some further investigation, we determined that this was an additional vector that the attack was using in an effort to exhaust our SSL processing capacity. We were able to respond quickly using our mitigation platform, but the countermeasures required significant tuning to reduce false positives which impacted legitimate customers. This resulted in approximately 25 more minutes of downtime between 23:05-23:30 UTC.
By 23:34 UTC, the site was fully operational. The attack continued for quite some time even once we had successfully mitigated it, but there were no further customer impacts.
What did we learn?
The vast majority of attacks that we've seen in the last several months have been volumetric in terms of bandwidth, and we'd grown accustomed to using throughput as a way of confirming that we were under attack. This attack did not generate significantly more bandwidth but it did generate significantly more packets per second. It didn't look like what we had grown to expect an attack to look like and we did not have the monitoring we needed to detect it as quickly as we would have liked.
Once we had identified the problem, it took us much longer than we'd like to mitigate it. We had the ability to mitigate attacks of this nature in our load balancing tier and in our DDoS mitigation platform, but they were not configured in advance. It took us valuable minutes to configure, test, and tune these countermeasures which resulted in a longer than necessary downtime.
We're happy that we were able to successfully mitigate the attack but we have a lot of room to improve in terms of how long the process takes.
We have already made adjustments to our monitoring to better detect and alert us of traffic pattern changes that are indicative of an attack. In addition, our robots are now able to automatically enable mitigation for the specific traffic pattern that we saw during the attack. These changes should dramatically reduce the amount of time it takes to respond to a wide variety of attacks in the future and reduce their impact on our service.
We are investigating ways that we can simulate attacks in a controlled way so that we can test our countermeasures on a regular basis to build additional confidence in both our mitigation tools and to improve our response time in bringing them to bear.
We are talking to some 3rd party security consultants to review our DDoS detection and mitigation capability. We do a good job mitigating attacks we've seen before, but we'd like to more proactively plan for attacks that we haven't yet encountered.
Hubot is able to route our traffic through our mitigation partner and to apply templates to operate our mitigation platform for known attack types. We've leveled him up with some new templates for attacks like this one so that he can help us recover faster in the future.
This attack was painful, and even though we were able to successfully mitigate the effects of it, it took us far too long. We know that you depend on GitHub and our entire company is focused on living up to the trust you place in us. I take problems like this personally. We will do whatever it takes to improve how we respond to problems to ensure that you can rely on GitHub being available when you need us.
Thanks for your support!
Nine Practical Pointers for Plodders
You will not make perfect plans. You will not work your plans perfectly. You’ll find a bog of ambiguity that you’ll need to step through carefully. There will be detours and delays. There will be equipment failures. You will spin your wheels. There will be unexpected phone calls and undesired emails. Social media will keep poking you for attention. Your indwelling sin and others’ indwelling sin will throw you curveballs. There will be some swings and misses. Your creativity won’t flow like you want it to when you want it to. And when you actually get to the project that you’ve scheduled time for at the time you scheduled it for, you won’t feel like doing it.
An Unconventional Desalination Technology Could Solve California's Water Shortage
By using sun as the fuel source, WaterFX uses roughly one-fifth of the electricity consumed by traditional desalination plants, according to Mandell. Less electricity means lower operating costs. With conventional desalination, electricity makes up 50-60% of the water costs, says Mandell. A typical desalination plant in San Diego operates at about $900 per acre-foot, while it costs around $450 to produce an acre-foot of water with WaterFX. (An acre-foot is 325,000 gallons, or the amount of water it takes to cover an acre at a depth of one foot).

How to Put an End to Bad Days
We also don’t think of our good days in the same way. We have a drive to get out of a bad mood, but we don’t have that same drive for good moods. The brain isn’t wired to react to good in the same, enthusiastic way it does to bad. That means we have to work twice as hard to make up for it.
Review: Google Glass Apps That Show the Device’s Promise | MIT Technology Review
There are still some big issues hampering the app. I was concerned about the app’s ability to accurately track speed, as the numbers on the display seemed to lag behind when I rode up and down hills. Strava might be able to improve on that, but the company can only optimize its app so much to make up for another big problem: Glass’s poor battery life (Google says it’s good for “one day of typical use,” though in my medium-to-heavy use I never got more than several hours out of it). After a relatively short ride from home to the ocean and back—about six miles—with frequent checks of my stats, Glass had lost a significant amount of power. To last through a multi-hour ride, you’d really want to limit these checks, which defeats the purpose of seeing such information in real time.
So you got a Raspberry Pi: now what?
When the Raspberry Pi was released earlier this year, the credit-card-sized Linux machine became an instant hit. The night it became available to order, both Premier Farnell/element14 and RS Components, the official distributors of the Pi project, exhibited the signs of a late '90s Slashdot effect: you could barely even get the two sites to load. Fast forward to today, and you can finally get your hands on one within three weeks. The Raspberry Pi is truly the Linux device of the year, if not the past decade. Follow past the break and we'll show you how to set yours up now that you've actually succeeded in snagging one.

Three Secrets Of The Only 5 Year Old iPhone Hit App
1) No Sequels . Unlike so many later hit franchises, “Doodle Jump” never got a sequel. This was a conscious move designed to prevent dilution and fragmentation of the core brand. Practically all mobile games now receive regular updates and expansion packs, but “Doodle Jump” more or less pioneered the concept. New seasonal or themed variations do affect game play and introduce some variation, but they never disrupt the original flow and feel of the game. Many majestic mobile game franchises have recently stumbled with sequels that have introduced unnecessary complications or sprawl. “Plants Vs. Zombies 2″ was a major stumble by Electronic Arts, tarnishing the crown jewel of its app range. “Angry Birds Star Wars II” has been widely criticized for having a confusing, opaque bonus and extra power system – and the four years younger Rovio game is actually now performing at par with the ancient “Doodle Jump” in the US iPhone chart. The no sequel rule is not without cost – as lucrative freemium games have proliferated, the $0.99 “Doodle Jump” has faded out of Top 500 in the US iPhone revenue chart.
There's No Right Way to Start Up
Silicon Valley and the tech world at large are filled with a variety of conventions. These conventions are now created, captured, and shared ad nauseam disguised as blog posts, tweets with links, and countless message boards. The benefit of such a canon is we all have access to a rich repository of knowledge — the cost, however, is we all, perhaps unwittingly, are exposed to the same suite of playbooks, which contain the same conventions, which could, if we’re not paying close attention, and especially when amplified in an echo chamber, trick us into believing a certain reality which, in turn, script our actions and lives down a path of predictability, or worse, mediocrity.
What Happens When You Zap Instant Film With 15,000 Volts | Wired Design | Wired.com
Critics often gush about a “heart-stopping” piece of art, but in Stearns’ case, it was almost a literal statement. When he first started experimenting with the neon transformer, he had a brush with catastrophe when electricity arced from one of his hands to the other. “It’s the volts that jolt, and the 15,000 volts certainly did, but it wasn’t terribly painful, just sudden,” he says. “If the current had been higher, it could have stopped my heart.” Since then he’s been far more fastidious about not touching the transformer while near grounded metal objects and had upgraded to a non-conductive workspace.
Hucksters and hustlers: inside the hidden brand orgy of SXSW
Half a decade ago, some of the brightest minds at South By Southwest Interactive came together to create the worst website in the world. Jeffrey Bennett proposed online image search for the blind. David Friedman pitched PeopleIPO, allowing anyone to buy shares in you. The winner, though, was Merlin Mann’s FlockdUp , an incomprehensible social network for “thought leaders” that seem to be constructed entirely of buzzwords. “FlockdUp is really uniquely positioned at this juncture to suction all of the oxygen out of this vertical, vis-a-vis an incredibly sticky, almost uncomfortably sticky, humid-weather-seated-on-a-vinyl-seat kind of approach to an accretive social network,” Mann told a rapt audience in Austin.
Microsoft Is Doing Us All A Favor By Killing Windows XP
The end is nigh. No, really. Less than a month from now Microsoft Microsoft will officially stop supporting the Windows XP operating system. Many security experts predict that it won’t be pretty for Windows XP users once the security patches stop rolling out, and some feel that pulling the plug on support is a mistake that will come back to bite Microsoft. The reality, though, is that Microsoft is doing us a huge favor that will make us all more secure—albeit with some potential short-term growing pains.

5 Steps to Mastering Tech Networking Events
Events will often share a list of attendees and their companies/industries ahead of time, and there will often be sponsors attending as well. If you notice that a particular company of interest will be attending, make a point to seek them out and talk to them about what it's like to work there — and don't be shy about asking if they're hiring. Referrals are far more effective than applying through job boards, so this can be one way of getting your foot in the door. Some startups don’t even post jobs they’re hiring for, and rely solely on referrals for recruiting — so it’s always smart to be aware of which startups will be attending. This way, you can master your pitch beforehand.

A Short Guide to the Internet’s Biggest Enemies
In the former category are some of the world’s worst offenders: Cuba, North Korea, China, Iran, Saudi Arabia, Vietnam, Belarus, Bahrain, Turkmenistan, Syria. Nearly every one of these countries has amped up their online repression in recent years, from implementing sophisticated surveillance (Syria) to utilizing targeted surveillance tools (Vietnam) to increasing crackdowns on online speech (Saudi Arabia). These are countries where, despite advocacy efforts by local and international groups, no progress has been made.

Delighting in the Greater Adoption
Every February, my family remembers my adoption day. We exchange flowers, hugs, tears, good memories, and love. Like other former orphans, I consider my adoption day a cause of great celebration. But how much greater and more worthy of celebration is our salvation and the greater adoption! Praise the Father that you are his own. Meditate on the implications of this great adoption for your life, the life of the body, and for those who don't call God their father. Thank the Lord that he redeemed you, encourage your brothers and sisters with the truths of the greater adoption, and seek to share this redemption and love with those who aren't yet God's children.
