I've just had the following mail from my dedicated provider regarding one of the servers:
I've asked for more information, and I've asked for a specific time and an estimated down time on this work.We have detected that the IPMI module of XXX.XXX.XXX.XXX is
defective and it must be replaced and reconfigured
by our team. To carry out this intervention,
it will be necessary to shutdown your server.
This module is necessary for restarting your server hardware
as well as the KVM over IP option.
Until this is repaired, you will not be able to reinstall your server.
If you do not respond, the intervention will be
performed within 10 days of sending this
