Brief outage for gitlab and xgitlab today at 4PM

We need to apply some updates and reboot the servers xgitlab.cels.anl.gov and gitlab.cels.anl.gov. This will happen at 4PM today. The outage shouldn’t take too long, but we’re scheduling an hour just in case. During this time, you won’t be able to visit or use repositories hosted there.
Let me know if this poses an undue inconvenience. Thanks!
