Maintenance: Exchange Reconfiguration

Message-Id: 201910241035
Time: Oct 26th, 2019, from 10 a.m.
Affected: Exchange users
Impact: Short connection losses

As part of the optimization work on the Exchange environment, a new,
very powerful load balancer has already been put into operation to
replace older hardware. On Saturday, October 26th, 2019, from 10 a.m.,
a second powerful load balancer will be integrated into the environment
to restore full redundancy. For a period of approx. 20 minutes,
interruptions of connections to the mail service are possible.

Work on the Exchange servers themselves will also take place on
Saturday and possibly Sunday. This may result in sporadically longer
response times.
