It is not entirely to do with the Democrats, Space Aliens, Mysterious Men in Black, or Arugula. In fact, this afternoon’s service interruption does not have a very exciting explanation.
Part of our caching service required an unscheduled restart. That means a slow rebuilding of data. You may notice some of the normal browsing related features (such as pagination) are missing while we repopulate the caching service. This is so we can get it done quicker.
Update: It’s not Groundhog Day but it sure feels like it. We are recovering today from the same problem as yesterday. This service interruption is our own fault. If you have questions that are only satisfied by technical answers please join our technical discussion forum on Google groups.
