The English Wikipedia has been experiencing painfully slow load times over the last few days, and lots of error messages when trying to save, to the point where the site has become difficult to use. There's discussion about it on the Village Pump, and someone has filed a bug report, but no one has any idea why it's happening, or whether it's being looked into. I would link to the discussion, but I can't get the page to open. Does anyone on the list have information about it? Sarah

en.wiki just slowed to a crawl and is now errored out. It has been going from normal to treacle slow all day. Tom On 18 May 2011 19:20, Sarah <slimvirgin(a)gmail.com> wrote:

I had problems with load times and time-outs, ever since the email notification was turned on. I asked the tech team if they were related, they didn't think so. Maybe, its a co-incidence, but did anyone notice if the slowness increased when email notifications were turned on?

Not 100% sure of that myself - I've been seeing more and more intermittent errors for over a week, probably nearly two weeks. Tom On 18 May 2011 19:24, Theo10011 <de10011(a)gmail.com> wrote:

It started for me on May 16. I don't know what date email notification started. Others at the PUMP began to report problems on the 10th, though that might have been a separate issue. It's really getting to the point now where it's hard to do anything.

Could someone from the Foundation or one of the developers say whether this is being looked into? Sarah On Wed, May 18, 2011 at 12:28, Thomas Morton <morton.thomas(a)googlemail.com>wrote;wrote:

I posted this on the English WP on April 11: http://lists.wikimedia.org/pipermail/wikien-l/2011-April/108899.html The responses I received suggested it might be a problem with my provider. I spoke with a Comcast tech. She considered the problem and concluded that I needed to clear my cache & cookies. This I did & it got better - for 1 day. Since then it has gotten back to being slower than ever. Marc on 5/19/11 9:52 AM, John at phoenixoverride(a)gmail.com wrote:

[Also posting to Bugzilla] According to the ops team, there are a number of separate and unrelated ops issues that have come up in the last few days: 1) Not all users are experiencing slowness, but a subset of users are. There's no definite smoking gun, but the most likely cause are ongoing issues with one of our routers in Tampa. The router will have to be taken down for maintenance to fix this issue, and order to perform this maintenance operation with minimal disruption, we need to have key ops engineers on standby to deal with any issues that may arise. My understanding is that the best available maintenance window is Tuesday next week. 2) There was a software deployment on May 18 which caused an application server overload; it was reverted the same day. 3) The mobile servers are currently intermittently overloaded, throwing internal server errors, and servers to provide additional capacity have been racked today. 4) In case you're looking at it, ganglia.wikimedia.org is not displaying correct server status information (as of yesterday); it's in the process of being fixed. We're still in the process of setting up a new primary data center location in Ashburn, VA, which will give us higher site reliability in general, and also create the possibility of safe failover in maintenance or emergency situations. -- Erik Möller Deputy Director, Wikimedia Foundation Support Free Knowledge: http://wikimediafoundation.org/wiki/Donate
