Normal wget redirect from mirror.accum.se | Generated by AI
Your wget command is hitting https://mirror.accum.se/mirror/wikimedia.org/dumps/... and getting a 302 redirect to https://laotzu.ftp.acc.umu.se/.... This is completely normal and expected behavior for the accum.se mirror — here’s why it happens and what it means:
Why the redirect happens
mirror.accum.se is only a redirector / load-balancer run by Academic Computer Club at Umeå University (ACC) in Sweden.
It does not host the files itself. Instead:
- It looks at your IP’s geolocation (or sometimes load)
- It automatically redirects you to the fastest/closest actual storage server in their mirror farm
- In your case it chose
laotzu.ftp.acc.umu.se(which is the real FTP/HTTP server that has the data)
This is the same system they have used for many years. Other common hostnames you might be redirected to are:
issac.ftp.acc.umu.selaotzu.ftp.acc.umu.se(the one you got)morpork.ftp.acc.umu.se- etc.
So even though you wrote mirror.accum.se in your script, you almost always end up downloading from one of the *.ftp.acc.umu.se back-ends.
Why you saw “206 Partial Content” on the first file
Because you (or someone/some script) already started downloading that exact same file before, wget -c detected the partial local file and sent a Range request. The server correctly resumed the download → 206 Partial Content. That’s good!
Is there any problem?
No. Everything is working as intended.
- The redirect is normal and harmless
- The final server (
laotzu.ftp.acc.umu.se) is still the official ACC/Wikimedia mirror - Checksums will be identical no matter which back-end server you get redirected to
If you want to avoid the redirect (optional)
You can skip the redirector completely and point directly to one of the real hosts, e.g.:
# These three are round-robined behind mirror.accum.se anyway
wget -c https://laotzu.ftp.acc.umu.se/mirror/wikimedia.org/dumps/enwiki/20251101/...
# or
wget -c https://issac.ftp.acc.umu.se/mirror/wikimedia.org/dumps/enwiki/20251101/...
But most people just keep using mirror.accum.se because the redirector automatically picks the best one for you.
TL;DR
Your script is fine. The 302 redirect from mirror.accum.se → laotzu.ftp.acc.umu.se is the normal, expected behavior of that mirror. Nothing is wrong, and you’re still downloading the authentic Wikimedia dump. Keep using mirror.accum.se — it’s one of the fastest and most reliable mirrors worldwide.
