Out of curiosity, if you ping the repositories first, then run apt-get
update, does it resolve properly and proceed with the update?
I had a problem (under Etch, IIRC, though maybe Etch -1) whereby I was
getting constant timeouts, both while trying to browse the web and
trying to run 'aptitude update'. It was an IPv6 problem and I solved it
by disabling IPv6 everywhere. But before I did that, I found that if I
pinged the repositories first, then ran the update, the update worked.
It was enormously frustrating. To this day, under Debian I still toggle
IPv6 lookups off in Iceweasel and Epiphany, to speed things up.
Otherwise, my browsers frequently sit for some seconds on "Looking
up..." before proceeding to download the page.
I only ever had this problem with Debian and Ubuntu, both installed on
my PC and my iMac. FreeBSD, Arch Linux, and OS X all work fine with
IPv6 enabled, even Gecko browsers (Firefox, Epiphany, and, on my iMac,
Camino) under those OS's are snappy without having to toggle off IPv6
lookups.
IMO -- my entirely unscientific uninformed opinion, I stress -- there's
something funky about Debian's networking stack.
