Geo: GitLab CE repository taking a long time to resync

I've been watching whether GitLab CE repository would resync on GPRD, since it gets updated quite frequently. It still hasn't:

=> #<Geo::ProjectRegistry id: 6601072, project_id: 13083, last_repository_synced_at: "2018-03-16 22:01:47", last_repository_successful_sync_at: "2018-03-02 09:53:59", created_at: "2018-02-26 18:14:20", resync_repository: true, resync_wiki: true, last_wiki_synced_at: nil, last_wiki_successful_sync_at: nil, repository_retry_count: 26, repository_retry_at: "2018-03-22 05:09:33", force_to_redownload_repository: true, wiki_retry_count: nil, wiki_retry_at: nil, force_to_redownload_wiki: nil, last_repository_sync_failure: "Invalid repository: no repository for such path", last_wiki_sync_failure: nil, repository_verification_checksum: nil, last_repository_verification_at: "2018-03-20 21:12:04", last_repository_verification_failed: true, last_repository_verification_failure: "Repository checksum mismatch: gitlab-org/gitlab-ce", wiki_verification_checksum: nil, last_wiki_verification_at: nil, last_wiki_verification_failed: false, last_wiki_verification_failure: nil>

I suspect the last failure was due to gitlab-com/migration#259 (closed), but with so many updates in the log event store, I would have thought we might schedule a new update before the next retry time.
