Nebula will take downtime for file system maintenance next week on Thursday, March 23rd from 10:00 AM until 3:00 PM. During the maintenance period all instances will be paused and the Horizon interface will not be available. The downtime is necessary to resolve ongoing issues with the Gluster file system on the storage nodes. Please report any issues or concerns by either sending e-mail to nebula@ncsa.illinois.edu (which will open a ticket) or writing a comment in the Nebula channel of the NCSA chat.
