Spam/DDoS attack
Incident Report for Status for Fathom Analytics
Resolved
Today, we tried out some new rules that were meant to reduce the strictness of our firewall. Unfortunately, the rule change meant huge amounts of spam was able to pass through, and we had to make a snap decision to go with a nuclear option, which was to clear the queue backlog (around 6 million pageviews), as 99% of traffic coming in was spam. Because of this, some sites lost up to 1.5 hours of traffic data.

If you weren't hit with spam, you'll see a tiny blip on your stats for today (between 6PM - 8PM PT). If you were hit with spam, you'll see a huge spike. If you were hit with the spam, please reach out us.

This isn't our first time dealing with spam, and we've invested a lot of time into spam protection. We'll be rolling out an additional firewall in Version 3 and, of course, we've reverted the rule change. We sincerely apologize for the inconvenience here. We have been under DDoS attacks since November 2020, and the series of events here were unfortunate.
