Wikipedia is down (isup.me)

Wikipedia sister sites are down as well.

en.wikiquote.org wikimedia.org

https://secure.wikimedia.org/ is up, but all the links provide "502 bad gateway"

Obligatory wikipedia: http://xkcd.com/903/

Mobile is up.

http://nagios.wikimedia.org/ looks like lots of the front-end machines are not responding

Not down here (mid-atlantic USA)

e: en.wikipedia.org that is

en.wikipedia.org is up.

https://www.wikipedia.org/ is up, search and links working.

It's back.
