Maintenance window for CELS GitLab services 2017-06-28 12:00 – 13:00

A maintenance window of our GitLab services has been planned for
2017-06-28 (Wednesday) from 12:00 to 13:00 (CDT) in order to update the
software.
GitLab services provided by gitlab.cels.anl.gov and xgitlab.cels.anl.gov
will be unavailable during maintenance.
Service is expected to be restored by 13:00, and may be available sooner
than that.
If this window poses undue inconvenience please let us know, we can
reschedule if needed.
