All this sounds like a problem with the provider ... traceroutes may be in order. : One problem is the mirrors themselves. There is no standard method for : mirroring or any policy.

Did you try http.us.debian.org? That's a round-robin DNS record dor several servers; there's a package whose name escapes me that will allow you to find the "best" one.

To avoid the Actually 63.209.15.252 recently had some sort of mirroring problem, it should be fixed now. Otherwise the top level mirrors at least stay quite well in sync. Jason

Try the mtr or traceroute command to see if it is not perhaps a server
inbetween you and ftp.debian.org. For me I am not having any problems.
Another good tool is netselect to find a mirror which is faster for you.
# netselect -vv ftp.debian.org ftp.us.debian.org http.us.debian.org \
http.us.debian.org debian.midco.net
ftp.debian.org 211 ms 12 hops 80% ok ( 8/10) [ 578]
ftp.us.debian.org 152 ms 15 hops 100% ok (10/10) [ 380]
http.us.debian.org 218 ms 13 hops 90% ok ( 9/10) [ 556]
http.us.debian.org 203 ms 12 hops 80% ok ( 8/10) [ 556]
debian.midco.net 183 ms 9 hops 90% ok ( 9/10) [ 385]
380 ftp.us.debian.org
You should also try and use the {http,ftp}.us.debian.org sites rather
than the straight {http,ftp}.debian.org sites for apt. The .us. sites
are on a round robin dns so will spread the load out over several
different sites.
# nslookup http.us.debian.org
Server: localhost
Address: 127.0.0.1
Non-authoritative answer:
Name:http.us.debian.org
Addresses: 209.249.97.234, 141.213.4.21, 63.209.15.252, 207.69.194.216
