Intermittent problems have hit both editors and readers of the Wikimedia Foundation projects recently. In an incident unrelated to the power outages of last week, servers have been suffering from large amounts of traffic - trying to fulfil so many requests at the same time that few are dealt with successfully and in a timely fashion. At the worst point, all Wikimedia Foundation projects simultaneously experienced these issues (unlike with similar outages, which have in the past affected only individual servers, limiting their negative effect). The exact cause is as of yet unknown, but preliminary investigations by the developers have suggested the source of the traffic was the Network File System (NFS) and not HTTP requests. This would rule out the idea of a simple external traffic spike, such as that which overloaded servers after the death of Michael Jackson recently.
Commons is still (Sunday) suffering from an image server overload, with some queries timing out, and others taking a disproportionate amount of time to complete. Disabling the CentralNotice has eased the problems in the interim. (Technical village pump). The Wikimedia Techblog also discusses the problem.
