Euler will be going offline to fix a critical filesystem issue today at 4pm. The maintenance period will last roughly 15 minutes. Currently running jobs should be unaffected, but users will be unable to connect until maintenance is complete.
I apologize for any inconvenience this may cause.
Regards,
Colin Vanden Heuvel
Euler Sysadmin
P.S. - I will send a migration status update after today's maintenance has completed.
