On May 17, 2022 at 08:16 AM ET, Gatsby Support was made aware that some customers were unable to authenticate to Gatsby Cloud because of a change in Gitlab authentication. This resulted in users unable to build their site.
The issue was resolved with a code fix in 10 hours.

Gitlab introduced a breaking change in their OAuth APIs without informing their partners and customers. The Gitlab auth endpoint would error out when receiving the old shape of the token data prior to version 15 which is what Gatsby and many other customers were using. This prevented us from pulling the necessary information needed to pull the user code, and build the site.
To fix our OAuth flow we added logic that pulled down a new auth token. For tokens where this was not the fix, we added a simple button to the Gatsby Cloud dashboard to refresh the tokens manually.
Unfortunately, builds would stop processing on the first step during the repository clone process when using Gitlab.
The authentication issue is now confirmed to be fully resolved.
Gatsby’s Engineering Team has successfully changed the logic of authentication with Gitlab and is monitoring to ensure this doesn’t occur again.
We’ve identified the authentication issue that occurred with Gitlab’s change and have applied logic to prevent this incident from happening again.
