bz and I both tried to push to mozilla-central and have been receiving this error consistently over the past 30 minutes:

I'm also failing to load the pushlog webpage:
http://hg.mozilla.org/mozilla-central/pushloghtml

I was getting this yesterday as well.  Other people were able to push while I was getting the error.

Comment 4

[Aravind Gottipati [:aravind]]

working on it, rebooting the backend servers.  They were pretty much dead.  The site should be coming back up now.  I am working on adding more backend servers to handle the traffic.

Possibly related, when pulling from comm-central I get:

abort: HTTP Error 502: Bad Gateway

Comment 6

[Aravind Gottipati [:aravind]]

Okay, servers should be up now and working.  Please comment here if you are still having problems committing.

Comment 7

[Aravind Gottipati [:aravind]]

This should be fixed now.  If you are interested, 550280 is tracking the "add more backend servers" effort.
