We introduced a bug in our indexing system at Oct 4, 2023 7:35 PM PST, which caused a corner case to double count events for 270 projects that have some special configs.

We are rolling back our index system and reprocess the data in the last 2 days. We expect the system to be fully recovered in a couple hours, at which point all double-counted events will be corrected.
