On July 9th 8pm UTC, Drupal.org will be migrating our Git server to a redundant cluster of 2 servers. This will provide failover in the event one server fails.
While we are working on the migration, users will not be able to commit files to Git or check files out of Git. We expect the migration to take up to 2 hours.
After the migration Host keys will change and your client might give an error message when pushing to Git. Consult your OS’s documentation on how to fix this error.
If you have any questions please raise an issue in the infrastructure issue queue. https://www.drupal.org/project/issues/infrastructure?categories=All
