Update timeline

  1. identified May 04, 2026, 01:45 PM UTC

    Due to problems with API indexing that occurred between 4/29 and 5/3, the current JSON snapshot for April 2026 is missing 1-2 days of data. We've resolved the indexing issue and are currently re-pushing the missing records into the API. Once that's completed, over the next few days, we'll build and release a new snapshot for April.

  2. identified May 05, 2026, 12:38 PM UTC

    The corrected JSON snapshot is in process. It will be completed and available in the next 2-3 days.

  3. resolved May 07, 2026, 12:34 PM UTC

    The corrected April 2026 JSON snapshot has been released.
