Unable to retrieve .dem files for recent public matches

[zhuliwen]

Description

I am encountering an issue where replay files (.dem) are unavailable for matches occurred between 2026-03-09 and 2026-03-10. While match_ids are successfully retrieved via the publicMatches API, the corresponding replay files cannot be downloaded, and the parsing process fails to produce a valid .dem URL.

Steps to Reproduce

1. Fetch recent matches using the /publicMatches endpoint.
2. Attempt to retrieve the replay_url for these match_ids.
3. Request a parse for the matches (if using OpenDOTA/STRATZ).
4. Observe that the replay file is either missing (404) or the parse request remains pending/fails to locate the source.

Expected Behavior

The API should return a valid .dem URL once the match has concluded, or the parser should be able to fetch the file from Valve's CDN.

Actual Behavior

• The .dem files are unreachable.
• Parsing requests do not result in a downloadable replay.
• Issue persists across multiple match_ids from the last 24 hours.

Sample Data (Example Match IDs)

• Match ID: [8721530888]
• Match ID: [8721006601]

Environment

• API Endpoint: https://api.opendota.com/api/publicMatches
• Timeframe: 2026-03-09 00:00 UTC to 2026-03-10

Additional Context

This seems to be a widespread issue for matches in this specific 24-hour window. I am unsure if this is due to a change in Valve's replay storage policy or a temporary downtime in the replay distribution network.
