DOWNTIME: servers and labs

[norman]

The whole Teaching Labs world will undergo some disruption over the next week or so:

• wolf (ssh server) is unavailable; it will be back later today,
• nxsrv (NX server) is unavailable; it will be back by Tuesday 5 September.
• dbsrv1 (database server) is unavailable; it will be back by Thursday 7 September.
• All labs are temporarily closed. BA 2210 will be open by Tuesday 5 September; other labs by Thursday 7 September.

All this has to do mainly with a major OS upgrade, from Ubuntu 14.04 to Ubuntu 16.04. As systems and labs become available again, they will be running the new version of the system.

Sorry for the disruption, and for the short notice.

We’ve run into more problems than expected in our upgrade to Ubuntu 16.04.
Here’s where things stand:

• wolf (ssh server) is up and running 16.04.
• Lab BA 2210 is open. BA 3175-3195 will open by 0900 on Friday 8 September.
• The remaining labs will open in a few days; watch this space.
• nxsrv (NX server) and dbsrv1 (database server) are still unavailable. We hope they’ll be back in a few days.

Sorry for the inconvenience of all this. This has been a rather more complicated upgrade than usual.
