howto avoid "apt-get update" going guru?

[Harald Dunkel <harald.dunkel@aixigo.de>]

Hi folks,

this morning I found "apt-get update" getting stuck due to an
unresponsive host:

# cat /etc/apt/sources.list
deb     http://ftp.debian.org/debian sid main contrib non-free
deb-src http://ftp.debian.org/debian sid main contrib non-free

# apt-get update
Err:1 http://ftp.debian.org/debian sid InRelease
  Could not connect to klecker-ftp.debian.org:80 (130.89.148.12), connection timed out [IP: 2001:6b0:e:2018::173 80]
Reading package lists... Done
W: Failed to fetch http://ftp.debian.org/debian/dists/sid/InRelease  Could not connect to klecker-ftp.debian.org:80 (130.89.148.12), connection timed out [IP: 2001:6b0:e:2018::173 80]
W: Some index files failed to download. They have been ignored, or old ones used instead.


I didn't mention klecker-ftp anywhere in my config files.
Its not on the round-robin list for ftp.debian.org either:

# host ftp.debian.org
ftp.debian.org has address 130.239.18.173
ftp.debian.org has address 130.239.18.165
ftp.debian.org has IPv6 address 2001:6b0:e:2018::165
ftp.debian.org has IPv6 address 2001:6b0:e:2018::173
ftp.debian.org mail is handled by 0 .


What would you suggest to avoid this kind of problem?


Every helpful comment is highly appreciated.
