The 9.15 push took nearly 30 minutes instead of the usual circa 10 minutes. Subsequent pushes (at least up until 10.30) have been equally slow. We are investigating the issue.
Ad serving continues, but campaign start/stop and updates may be somewhat delayed.
We apologize for the inconvenience. Updates will follow.
Update: the problem was due to excessive amounts of log data being read for certain forecasts. The issue was resolved on Friday May 22nd.
