Incident Notice - Sentiment Gap on 2026-03-18
Affected window: 2026-03-18 ~16:40 UTC to ~18:52 UTC (~2 hours)
What happened: X (Twitter) rotated all internal API endpoint identifiers for the second time in 10 days (previous occurrence: March 8). Additionally, X changed the structure of its page scripts, breaking the authentication header generation that occurs before any API call can be made. This caused immediate failures on every request — no new X (Twitter) sentiment data was collected during the affected window. Market data (price, volume, microstructure) was unaffected and is complete for this period.
Impact on the dataset:
- Coins that could not be matched with fresh sentiment data were not admitted into the watchlist during this window. This is by design - the pipeline requires complete data for every snapshot, so no partial or incomplete entries were produced.
- Snapshot volume for this window is reduced compared to normal operation
- Approximately 2 hours of X (Twitter) post collection is missing from the archive
Resolution: The pipeline was repaired and returned to full operation at ~18:52 UTC on March 18, 2026. All 7 collection accounts recovered successfully. Additional safeguards were implemented to prevent cascading failures if this type of breakage recurs.
For researchers: If you are working with March 18, 2026 data, expect lower snapshot volume in the 16:40-18:52 UTC window. All snapshots that do exist are complete and fully validated - no fields are missing or degraded.
