(My apologies if so, as I haven't been > following closely.) it's not a stupid question. But as you can see from the notes above, DNS on its own and TCP on its own are *not* mega-slow. This is what has me stumped. But sure, a traceroute wouldn't hurt. Here's what i get to the test server we've been using: >>> 0 dkg@pip:~$ traceroute nytimes.com >>> traceroute to nytimes.com (199.239.136.200), 30 hops max, 60 byte packets >>> 1 splat.lair.fifthhorseman.net (192.168.13.1) 0.479 ms 0.384 ms 0.346 ms >>> 2 er1.nyc1.speakeasy.net (216.254.115.1) 10.477 ms 13.184 ms 18.252 ms >>> 3 110.ge-0-0-0.cr1.nyc1.speakeasy.net (69.17.83.213) 20.059 ms 20.518 ms 20.890 ms >>> 4 444.ge-3-3-0.mpr1.lga3.us.above.net (208.184.48.178) 15.247 ms 15.931 ms 17.337 ms >>> 5 above-qwest.lga5.us.above.net (64.125.13.246) 18.301 ms 18.992 ms 21.435 ms >>> 6 * * * >>> 7 nyc-edge-03.inet.qwest.net (205.171.217.26) 25.186 ms 8.844 ms 10.333 ms >>> 8 * * * >>> 9 * * * >>> 10 * * * >>> 11 * * * >>> 12 * * * >>> 13 * * * >>> 14 * * * >>> 15 * * * >>> 16 * * * >>> 17 * * * >>> 18 * * * >>> 19 * * * >>> 20 * * * >>> 21 * * * >>> 22 * * * >>> 23 * * * >>> 24 * * * >>> 25 * * * >>> 26 * * * >>> 27 * * * >>> 28 * * * >>> 29 * * * >>> 30 * * * >>> 0 dkg@pip:~$ Steve, what do you see when you're using one of the networks on which iceweasel gives you trouble? --dkg
