A couple of issues have been affecting phabricator.wikimedia.org since last week and are only partially mitigated. I'd like to provide a brief summary of the current status for those who haven't been following along closely:

1. There were several incidents of vandalism by apparently manual or semi-automated means. In response, phabricator admins took steps to limit further damage. The most visible consequence of this is that we have temporarily enabled manual approval of new accounts. This means that all newly-created accounts must be approved by an admin before they can use phabricator. We will approve any and all accounts which appear to be legitimate users but there might be some delay as we have a limited amount of time to devote to reviewing new accounts.

2. The recent gerrit upgrade had unexpected consequences for Phabricator's git repository mirroring functionality. Because gerrit was migrated to "notedb," a lot of new meta-data was exposed via git references. Phabricator was unable to mirror the new metadata without hitting some timeouts and as a result, many git repositories were failing to import into Phabricator. This has been mostly resolved now, however, there may still be some repositories which are failing to update. Please report any issues that you encounter on the associated task: https://phabricator.wikimedia.org/T196855
