Thursday (6th of June) at 10:00 we will implement some code changes and move the HWBOT engine from servers. The first takes half a minute, but the latter will cause a downtime between 10:00 and 11:00.
Some issues logged on the hwbot issue tracker will be solved with the new patch.
The maintenance has been postponed until the 6th of June, this thursday.
Downtime will start in 10 minutes
