Fram is in service again

Dear Fram users,

after more than 16 days of downtime, losing more than 12 million CPU hours, we were finally ready to return the system to service tonight.

This downtime has been a very unpleasant experience to us, and we sincerely understand that this has been annoying and causing distress to our users depending on the service.

The main reason for the downtime has been severe problems with the global file system on Fram, forcing us to halt the system and escalate towards the file system vendor until their engineers were able to analyse and repair the different issues experienced.

Sincerely, Jørn Amundsen, UNINETT Sigma2 AS
