Tuesday 15/07 9:30-11:30 - maintenance on some DICE remote desktop servers
Servers guitar, theorbo and zither will be unavailable while they get important updates to maintain security and system integrity.
You can find out which remote desktop server you use with the DICE command:
host $USER.remote.inf.ed.ac.uk
On other systems replace $USER with your DICE username.
Other remote desktop servers won't be affected. Anyone who has their own DICE desktop can access its remote desktop through the Informatics VPN, and staff can also use staff.xrdp.inf.ed.ac.uk.
