Hey folks, is anyone aware of any problems happening right now with Layer42, or within the PAIX?
We're seeing issues reaching both www.google.com (going through the PAIX) as well as www.facebook.com (going through the PAIX). Packets not going through the PAIX appear to be working fine.
FWIW, my connectivity via Layer42's network (at their 1555 Plymouth (MV) facility) appears to be fine, including to www.'('facebook'|'google')'.com. Same appears true via IPv4 and IPv6.
True as of 21:20 GMT-7. I didn't get your email until just now, so perhaps there was a problem that has since cleared up.
The problem hasn't cleared up. Instead, it appears in both cases someone has induced reconvergence/route priority to route *around* the PAIX. It looks like San Jose is now exclusively in use. Here's what mtrs look like to both Google and Facebook; compare them to the previous. |------------------------------------------------------------------------------------------| | WinMTR statistics | | Host - % | Sent | Recv | Best | Avrg | Wrst | Last | |------------------------------------------------|------|------|------|------|------|------| | fw01.noc.sv2.tellme.com - 0 | 71 | 71 | 0 | 0 | 3 | 0 | | gw01.nocport.cns.sv2.tellme.com - 0 | 71 | 71 | 1 | 2 | 12 | 1 | | gw02.edgecross2.cns.sv2.tellme.com - 0 | 71 | 71 | 1 | 2 | 19 | 1 | | gw-tellme.sv.svcolo.com - 0 | 71 | 71 | 2 | 3 | 12 | 2 | | xe1-5-901.core1.sv1.layer42.net - 0 | 71 | 71 | 2 | 6 | 62 | 4 | | sv1.br01.sjc1.tfbnw.net - 0 | 71 | 71 | 3 | 6 | 83 | 3 | | ae1.bb02.sjc1.tfbnw.net - 0 | 71 | 71 | 4 | 5 | 23 | 5 | | ae2.dr01.snc5.tfbnw.net - 0 | 71 | 71 | 4 | 7 | 71 | 4 | | po510.csw02a.snc5.tfbnw.net - 0 | 71 | 71 | 4 | 5 | 12 | 4 | | www-13-02-snc5.facebook.com - 0 | 71 | 71 | 4 | 4 | 13 | 4 | |________________________________________________|______|______|______|______|______|______| |------------------------------------------------------------------------------------------| | WinMTR statistics | | Host - % | Sent | Recv | Best | Avrg | Wrst | Last | |------------------------------------------------|------|------|------|------|------|------| | fw01.noc.sv2.tellme.com - 0 | 21 | 21 | 0 | 0 | 2 | 1 | | gw01.nocport.cns.sv2.tellme.com - 0 | 21 | 21 | 1 | 1 | 12 | 4 | | gw02.edgecross1.cns.sv2.tellme.com - 0 | 21 | 21 | 1 | 3 | 11 | 1 | | gw-tellme.sv.svcolo.com - 0 | 21 | 21 | 3 | 4 | 12 | 7 | | xe1-5-901.core1.sv1.layer42.net - 0 | 21 | 21 | 3 | 5 | 12 | 8 | | eqixsj-google-gige.google.com - 0 | 21 | 21 | 3 | 7 | 56 | 10 | | 216.239.49.168 - 0 | 21 | 21 | 3 | 6 | 14 | 9 | | 64.233.174.119 - 0 | 21 | 21 | 3 | 5 | 12 | 10 | | 74.125.224.144 - 0 | 21 | 21 | 3 | 4 | 12 | 8 | |________________________________________________|______|______|______|______|______|______| So, anyone know what's going on in the PAIX? :-) -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, US | | Making life hard for others since 1977.
