old-releases.ubuntu.com servers return different content

[Alexander Turenko]

I'm looking for Ubuntu Groovy mirrors at old-releases.ubuntu.com and found that sometimes I receive 404 HTTP code, but sometimes it works. Digged down to difference in responses from different servers behind old-releases.ubuntu.com.

$ dig +short old-releases.ubuntu.com
91.189.91.123
91.189.88.248
91.189.91.124
91.189.88.247

$ curl -Ssf --verbose --resolve old-releases.ubuntu.com:80:91.189.91.124 http://old-releases.ubuntu.com/ubuntu/dists/ 2>&1 | grep 'port 80\|groovy/'
* Connected to old-releases.ubuntu.com (91.189.91.124) port 80 (#0)

I didn't find an appropriate project for this bug report and chose debmirror as one that looks most related. If it is inappropriate project for this bug report, please direct me to the right one.

Status changed to 'Confirmed' because the bug affects multiple users.

It looks resolved now. At least I see 'groovy' directory on all IP addresses reported by `dig`.
