media.ccc.de in confused state about some 38C3 uploads

[HW42]

The mirror management seems to be in a confused state about some of the recent 38C3 uploads.

I have seen this with different files, arbitrary example:

https://media.ccc.de/v/38c3-security-nightmares under Downloads links to https://cdn.media.ccc.de/congress/2024/webm-sd/38c3-533-deu-eng-Security_Nightmares_webm-sd.webm

When trying to download I get redirects (from multiple tries):

https://silo.ffmuc.net/38c3/congress/2024/webm-sd/38c3-533-deu-eng-Security_Nightmares_webm-sd.webm
https://media.nurluefter.de/congress/2024/webm-sd/38c3-533-deu-eng-Security_Nightmares_webm-sd.webm
https://ftp.halifax.rwth-aachen.de/ccc/congress/2024/webm-sd/38c3-533-deu-eng-Security_Nightmares_webm-sd.webm

Only the last mirror actually has the file. Others deliver an 404 error.

If I look at the directory listing at https://cdn.media.ccc.de/congress/2024/webm-sd/, I see:

38c3-533-deu-eng-Security_Nightmares_webm-sd.webm  02-Jan-2025 00:20           216476191

But when looking at the https://cdn.media.ccc.de/congress/2024/webm-sd/38c3-533-deu-eng-Security_Nightmares_webm-sd.webm?mirrorlist it says:

The file /congress/2024/webm-sd/38c3-533-deu-eng-Security_Nightmares_webm-sd.webm has a size of 0.0 bytes (0 bytes) and was last modified on Mon, 01 Jan 0001 00:00:00 UTC.

So clearly something is in a somewhat confused or half-uploaded state.

Might be the same as reported in #754, but since that one has been closed by the reported, and it's not obvious if it's the same or a different error, I'm opening a new issue.

PS: The above is what I observed within the last 30 min or so (as of 2025-01-03 00:20 +01:00).

This was a temporary issue while our cdn was effectively down and some emergency fallback redirects™ were in place.
