On Sunday, March 16, 2025 between 4am and 8am, the University of Maryland Division of Information Technology will conduct a set of disaster recovery network resiliency tests that could cause intermittent service interruptions to DEP. This is a regular annual activity and it generally results in no discernable impact or at worst several seconds of connection interruptions over the entire duration of the test.

March 4, 2025 – WMATA Fare and Secondary Location for Event Data Added

On March 4, 2025, the DEP now includes WMATA fare data added in a new section called <fares> which contains the fare amounts based on destination from the current stop. This data only shows up in the GTFS requests that use the type stop since fares are associated with each stop.
