Maintenance window for GitLab services 2017-05-07 (Sunday)

A maintenance window of our GitLab services has been scheduled for
2017-05-07 from 13:00 until 16:00 to migrate the services to new
servers.
During the maintenance window, both gitlab.cels.anl.gov and
xgitlab.cels.anl.gov will be inaccessible via the web interface.
Users will still be able to clone, pull and fetch from a git repository,
but write access (e.g. ‘git push’) will be disabled, preventing data
from getting out-of-sync.
Service is expected to be restored by 16:00 on 2017-05-07 and we will
announce when the work has been completed.
If this maintenance window poses an undue inconvenience, please let us
know, it can be rescheduled if necessary.
Please let me know if you have any questions.
Chris
