Same here too...i don't know if having a direct peering with Edgecast will solve the issue. -- Tassos Brian Keefer wrote on 8/11/2012 05:08:

IPv4 content does work fine, using the IPv6 literal returns a 404 which is small enough to fit in a smaller 1480 byte MTU. I have another test site that has a clean 1500 byte mtu and I can fetch the s0.wp.com page from there. It looks like tunneled IPv6 users might be in hurt here. Is anyone else experiencing similar issues? My traceroute shows they are employing a CDN for s0.wp.com, so not everyone might be affected. 7 asd2-rou-1022.NL.eurorings.net (2001:680:0:800f::291) 6.460 ms 6.203 ms 6.188 ms 8 asd2-rou-1044.eurorings.net (2001:680::134:222:85:63) 6.447 ms 6.494 ms 6.495 ms 9 adm-b5-link.telia.net (2001:2000:3080:6f::1) 6.818 ms 6.936 ms 6.891 ms 10 ldn-b3-v6.telia.net (2001:2000:3018:5::1) 15.290 ms 27.481 ms 15.380 ms 11 edgecast-ic-147468-ldn-b3.c.telia.net (2001:2000:3080:378::2) 15.116 ms 15.174 ms 15.176 ms 12 2606:2800:234:1922:15a7:17bf:bb7:f09 (2606:2800:234:1922:15a7:17bf:bb7:f09) 15.496 ms 15.327 ms 15.460 ms Kind regards, SethExact same issue here over HE.net tunnel. I can get errors from the (presumably) front-end proxy, but content stalls forever. I'm seeing this for all WP related requests that go to EdgecastCDN. -- chort
