January 31, 2024 – Real-Time NWS Weather Alerts Unavailable [Resolved on 4/30/2024]
On January 31, 2024, the DEP automated monitoring system detected an outage caused by National Weather Service (NWS) change to their API for the NWS Weather Alerts. This change resulted in NWS Weather Alerts no longer being ingested into DEP and no longer available in the DEP API in real-time. Historical data prior to January 31, 2024, is still available in the DEP. The current resolution time is unknown.

October 20, 2023 – Transurban Detector Data Outage [Resolved on 2/15/2024]
Starting around October 20, 2023, the DEP automated monitoring system detected a drop in the number of detector data records arriving to DEP resulting in less than 1% of expected data being available in DEP. Transurban resolved the issue on December 3, 2023. Currently there is a gap in Transurban detector data for this time period. Transurban has provided a backfill that is expected to be processed and DEP gap eliminated by February 16, 2024.
