Github was down

Quick! Everyone jump to conclusions!

"18:14 UTCWe are investigating issues with requests timing out when visiting GitHub.com" - https://status.github.com/

A traceroute seems to get to lb1b-ext.rs.github.com successfully so it seems to be an issue on their end.

edit: 18:18 UTCWe are investigating issues with the load balancers in front of GitHub. We will provide an update once we have more information.

Status messages here https://status.github.com/messages

And it's back.

The status page itself seems to be timing out, too, at least for me.

they just posted an update

It's back.
