ESAMS Servers not reachable, some EU traffic affected. (Fixed!)

Starting approx. 03:20 GMT, servers in our ESAMS facility began to roll offline one after another.  After some investigation, it appea

rs power is not being supplied to all the servers.  This has resulted in some slow downs for traffic of EU users.

We have temporarily migrated all traffic to our primary FL datacenter.  Once the servers are

back online in ESAMS, we will be pushing service back to it as well.

Update: The problem has been identified and finally fixed. Traffic has been returned to normal.

The best guess so far is that there was a cooling failure in the datacenter which caused the Sun boxes to shut themselves down.

An update from Leaseweb/Evoswitch is here:

Please note that while the toolservers are indeed housed in the racks with Wikimedia servers, they are a separate management issue. They have root users and admins that the Wikimedia cluster does not.

So yes, they should be online, but they are also not directly administered by all of the Wikimedia sysadmins.

Any toolserver related issues should be addressed in the #wikimedia-toolserver IRC channel. has further information.

Nice to hear that it’s “Fixed!” But then why is the urgently needed Toolserver still down?
