English Wikipedia brief outage

Translate this post

We had a crash on our database master for English Wikipedia. Domas is restarting it and swapping it out for another master server; should be back online in a few minutes.
In the meantime, Wikipedia in other languages and all other Wikimedia sites remain unaffected.


Update 23:39 UTC: We’re back! Looks like approximately 25 minutes of breakage.

An out-of-memory condition on the database master server ended up killing the MySQL daemon…

Uh oh, Brion is blogging in a crisis!

It just came back up for me!

Was this error only appearing on db modifications, or on everything?
As usual with site outages, I missed it 😀

Would have hit darn near everything, but if you weren’t logged in you might not have noticed.

No donation notice? But downtime is our most lucrative product!

Indeed. We really should add a PayPal link there 😛
