[ros-general] Server downtime on Saturday

[Colin Finck]

Hi all,

In the process of improving the performance of our infrastructure, we
will upgrade the first of two servers this Saturday.
This will result in a downtime for the following services:

* SVN
* Mail and mailing lists
* BuildBot
* Testman
* GIT mirror
* File server at svn.reactos.org
* Compatibility Database
* ev.reactos.org
* Second nameserver
* RosKGB bot

The upgrade will in particular increase CPU performance as well as RAM
and HDD sizes, so we will have more resources available afterwards.
Our current server has served us well since 2009, so don't expect such
an upgrade to happen again in the next few years.

We're aware that this affects many core services, so we will do our best
to keep the downtime as low as possible. Our target is <12h.
Gladly, we have already done such an upgrade in the past, so it mainly
boils down to the speed of transferring files over the network.
Meanwhile, we apologize for the caused inconveniences.

With best regards and on behalf of the whole infrastructure team,

Colin Finck
