Summary:

During the maintenance a hypervisor will be reinstalled.

Because of this, network statistics will be offline during the maintenance and the database cluster behind the BIT website, webmail, filesender and email settings in the portal will lose redundancy during the maintenance. It will also choose a new master server, which will cause a short interruption in these services of at most a few seconds.

Details:

During the maintenance a hypervisor will be reinstalled. Some virtual machines with local storage will have to be shut down.

The server for network statistics will be offline during the maintenance. The page with statistics will be available but the statistics will not update during the maintenance.

The redundant database cluster behind the BIT website, webmail, filesender and settings for email accounts in the portal will lose redundancy during the maintenance because one out of three servers will be offline. This will also cause a master election, which will cause a short interruption of these services for a few seconds.
