Hi, I think there may be a problem with the ubuntu build engines on Jenkins. The ubuntu2, ubuntu3, ubuntu4, and ubuntu5 build engines are all offline, and don't seem to be coming back online to service the build queue. The ubuntu1 engine is online and running two builds, but one has been running for ten hours, and the other since August 9th, so I suspect they may be hung.
(Actually, at the moment I'm getting 502 errors from https://builds.apache.org/, so I can't even see the build queue, but it was looking unhealthy last time I checked.) Thanks! Holly
