on the 16th this around 23:00 GMT TS will be brought down due to an upgrade of the Hypervisors that VM is running on.
Downtime can be up to 8 hours. Hopefully a lot less, but one never knows.
For the first time we are asking the good people that deliver the upgrade to do it for us, but I will be on duty to pay close attention to what they are doing (yah, overtime!).
