We’re not sure who GitHub pissed off but they are having one hell of a week with four outages in five days and two separate Denial of Service attacks. Currently they are being hit with another DDoS attack, the second one in two days. The site is currently hobbled but not down and out (but if everyone jumps over there to check it out it will probably crater).

Yesterday GitHub was down for over an hour and a half while engineers shut down port 80 in an attempt to slow down a DDoS strike. They have yet to release details on the origin of the attack but we’re guessing it’s those pissed-off Ruby on Rails Russian hackers coming back to claim their turf.

Here’s snippets from GitHub’s service status page:
