The status messages might fool you: https://status.github.com/messages but repos like Seldaek/monolog, doctrine/dbal, and a lot of the symfony ones (config, console, form, security, translation, validation). Are all down and have been continuously for about 19 straight hours now). I find it hard to believe that these are all part of the 3% slice they claim was affected or even more so that they were all part of the 0.2% and 0.18% they claimed had all been restored.
This raises a good question about the use of tools that depend on Github like composer for PHP dependencies. How unwise it is to depend on such an undependable system for anything, especially code/application dependencies! Especially for versioned releases other mirrors would be essential. Of course, the lesson to be taken away: always commit code to your own repo. It's the only way to make sure you have control of it. Take vendor/* out of .gitignore in the case of composer. Sad, but true.
