About every second day now, my ADSL broadband connection turns to sludge. Just loading the ABC news homepage, or BBC, or anything else, takes up to a minute, or sometimes stalls indefinitely. Power cycling the ADSL modem sometimes fixes this problem, and also the times when DNS stops working, i.e. the stall is during "Looking up ...". I just did that now, without improvement, but hitting the "Reload Current Page" icon in firefox sometimes helps. In firefox, I have network.dns.disableIPv6 = "user set boolean true", but that's more for slow "Looking up ..." AIUI, whereas it's glacial page transfers which make the service almost useless at the moment. The link looks more than OK: Connection Status Connected Us Rate (Kbps) 128 Ds Rate (Kbps) 1536 US Margin 27 DS Margin 21 Trained Modulation T1413 LOS Errors 0 DS Line Attenuation 54 US Line Attenuation 31 Peak Cell Rate 301 cells per sec CRC Rx Fast 3 CRC Tx Fast 1 CRC Rx Interleaved 0 CRC Tx Interleaved 0 Path Mode Fast Path /proc/sys/net/core/rmem_default is 112640 /proc/sys/net/core/rmem_max is 131071 Repeated long latencies within Internode's network don't look like they'd help much, but I don't have anything to compare that with. The fact that it seems to have failed to get to the target in the end looks ghastly, and beyond my fixit toolkit. $ traceroute www.linuxcnc.org traceroute to www.linuxcnc.org (69.163.248.64), 30 hops max, 60 byte packets 1 router (192.168.1.254) 1.110 ms 1.313 ms 1.532 ms 2 lns20.mel4.internode.on.net (150.101.212.44) 16.206 ms 22.500 ms 29.324 ms 3 te2-2.cor3.mel4.internode.on.net (150.101.208.65) 36.055 ms 42.548 ms 49.196 ms 4 gi6-0-0.bdr1.mel4.internode.on.net (150.101.210.41) 225.556 ms 231.354 ms 238.425 ms 5 te5-0-0.bdr1.syd6.internode.on.net (150.101.208.106) 250.423 ms 253.429 ms 257.861 ms 6 pos1-0-0.bdr1.lax1.internode.on.net (203.16.213.190) 263.005 ms 269.143 ms 274.384 ms 7 144.223.30.1 (144.223.30.1) 282.270 ms 183.912 ms 183.287 ms 8 sl-st31-la-0-0-3-0.sprintlink.net (144.232.5.100) 187.641 ms 194.321 ms sl-st31-la-0-4-2-0.sprintlink.net (144.232.5.102) 200.827 ms 9 144.232.24.222 (144.232.24.222) 207.956 ms 144.232.9.46 (144.232.9.46) 184.232 ms 144.232.24.222 (144.232.24.222) 190.154 ms 10 te0-2-0-2.ccr22.lax01.atlas.cogentco.com (154.54.29.201) 197.100 ms te0-3-0-5.ccr22.lax01.atlas.cogentco.com (154.54.44.133) 183.526 ms te0 (154.54.29.201) 181.851 ms 11 te8-1.mag01.lax01.atlas.cogentco.com (154.54.28.146) 236.065 ms 238.283 ms 239.757 ms 12 38.122.20.218 (38.122.20.218) 207.794 ms 214.622 ms 183.125 ms 13 ip-66-33-201-114.dreamhost.com (66.33.201.114) 204.995 ms * * 14 * * * ... 30 * * * Unless they're just hosted on dreamhost, and local firewalls are intervening?
