GitLab database goes out after spam attack

The company today said it lost six hours of database data, including issues, merge requests, users, comments, and snippets, for and was in the process restoring data from a backup. Data was accidentally deleted, according to a Twitter message.

As part of our ongoing recovery efforts, we are actively investigating a potential data loss. If confirmed, this data loss would affect less than one percent of our user base, and specifically peripheral metadata that was written during a six-hour window," the company said. "We have been working around the clock to resume service on the affected product, and set up long-term measures to prevent this from happening again. We will continue to keep our community updated through Twitter, our blog and other channels."

"This happened because there was a spike in writes that were not processed on time by the secondary database." GitLab has been dealing with a series of database issues, including a refusal to replicate. went down at 6:28 pm PST on Tuesday and was back up at 9:57 am PST today, said Tim Anglade, interim vice president of marketing at the company.
