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.
