Description Mark A. Hershberger 2014-02-20 17:50:07 UTC
When going to

I got a page that only displayed:
  [3592a8e3] 2014-02-20 17:46:43: Fatal exception of type MWException

Comment 3 Mark A. Hershberger 2014-02-20 18:09:07 UTC
It seems to be sporadic and not consistently happening.  But it is happening quite a bit (as in more than once an hour).

Comment 6 Greg Grossmeier 2014-02-20 18:56:47 UTC
The updated version of scap is having some problems right now during the weekly major upgrade (ie: we cut the new wmf15 branch this morning, so new i10n messaging and all that).

The MediaWiki Core team is on it. You can see progress in #wikimedia-operations on Freenode.

Sorry about this, will update when there's more.

Temporary update: Things should be back to normal for now. We will attempt another deployment when we are comfortable we won't hit this problem again.
Comment 9 Bryan Davis 2014-02-20 21:32:10 UTC
The scap problem was that all hosts in the cluster (across both datacenters) were calling tin's rsync server. This bug was fixed in
