[Fake?] Notice of customer SSO on git push

I have a regular repo with a gmail account but today on git push I get this notice which I think might be some sort of attack or spam. Strangely my repo is private and I want to know if this is just a spam/attack on my repo or something affecting wide range of users? Generally what is its security entails?

Earlier today, a banner intended for a subset of users was enabled on GitLab.com. Due to a bug, this banner was displayed to anyone who pushed code through the command line to GitLab.com. The issue was quickly resolved and the banner was removed.

The banner message was cosmetic only, published by GitLab, limited to the Git push and did not affect or share any repository or user data.

Note: some of the contents of this post were edited to protect the privacy of GitLab’s users.
