google imap timeouts / slowness from Toronto Canada ?
Anyone else seeing google imap timeouts / slowness ? We hit their services in Toronto Canada for ipv6 and ipv4 via gtt (However, ipv4 seems to come back via Torix). I am not seeing packet loss, just a lot of slowness in response at the app layer. google status says all ok. Problems started around 3:30am EST. My traffic comes out of AS11647. tcp acks come back super quick. Just random delays in the Push of the app response. example pcap below of "slow" and one "normal" traceroute6 to imap.gmail.com (2607:f8b0:4004:c1b::6d) from *2607:f3e0::12*, 64 hops max, 16 byte packets 1 host6 0.169 ms 2 toronto-torix-6 7.452 ms 3 * 4 google-b.ip6.torontointernetxchange.net 5.442 ms 5 2001:4860:0:1::322f 5.456 ms 6 2001:4860:0:1::3244 6.075 ms 7 2001:4860::c:4002:fc1a 27.485 ms 8 2001:4860::c:4002:6523 26.352 ms 9 2001:4860::c:4002:332e 26.528 ms 10 2001:4860::c:4002:a29a 27.551 ms 11 2001:4860::cc:4001:efe0 55.962 ms 12 2001:4860:0:1::e63 26.644 ms 13 * 14 * 15 * src ip 64.7.153.12 2 gtt-core1-10G (67.43.129.247) 5.225 ms 3 ae4-68.cr5-tor1.ip4.gtt.net (69.174.3.205) 7.868 ms 4 ae2.cr2-tor1.ip4.gtt.net (141.136.105.230) 10.595 ms 5 74.125.147.196 (74.125.147.196) 8.620 ms 6 192.178.98.45 (192.178.98.45) 8.997 ms 7 192.178.98.54 (192.178.98.54) 8.943 ms 8 142.251.231.171 (142.251.231.171) 18.056 ms 9 142.251.68.58 (142.251.68.58) 21.095 ms 10 142.251.69.191 (142.251.69.191) 27.531 ms 11 142.251.226.101 (142.251.226.101) 27.294 ms 12 216.239.57.97 (216.239.57.97) 27.101 ms 13 142.251.245.105 (142.251.245.105) 27.056 ms 14 * 15 * slow 12:27:25.602118 IP6 2607:f3e0::12.56498 > 2607:f8b0:4004:c19::6c.993: Flags [S], seq 3558477261, win 65535, options [mss 1440,nop,wscale 6,sackOK,TS val 366746043 ecr 0], length 0 12:27:25.629789 IP6 2607:f8b0:4004:c19::6c.993 > 2607:f3e0::12.56498: Flags [S.], seq 3828362457, ack 3558477262, win 65535, options [mss 1440,sackOK,TS val 998507935 ecr 366746043,nop,wscale 8], length 0 12:27:25.629824 IP6 2607:f3e0::12.56498 > 2607:f8b0:4004:c19::6c.993: Flags [.], ack 1, win 1026, options [nop,nop,TS val 366746071 ecr 998507935], length 0 12:27:25.630041 IP6 2607:f3e0::12.56498 > 2607:f8b0:4004:c19::6c.993: Flags [P.], seq 1:206, ack 1, win 1026, options [nop,nop,TS val 366746071 ecr 998507935], length 205 12:27:25.657752 IP6 2607:f8b0:4004:c19::6c.993 > 2607:f3e0::12.56498: Flags [.], ack 206, win 261, options [nop,nop,TS val 998507963 ecr 366746071], length 0 12:27:25.659493 IP6 2607:f8b0:4004:c19::6c.993 > 2607:f3e0::12.56498: Flags [.], seq 1:1209, ack 206, win 261, options [nop,nop,TS val 998507965 ecr 366746071], length 1208 12:27:25.659504 IP6 2607:f8b0:4004:c19::6c.993 > 2607:f3e0::12.56498: Flags [P.], seq 1209:2417, ack 206, win 261, options [nop,nop,TS val 998507965 ecr 366746071], length 1208 12:27:25.659518 IP6 2607:f3e0::12.56498 > 2607:f8b0:4004:c19::6c.993: Flags [.], ack 2417, win 988, options [nop,nop,TS val 366746100 ecr 998507965], length 0 12:27:25.659617 IP6 2607:f8b0:4004:c19::6c.993 > 2607:f3e0::12.56498: Flags [.], seq 2417:3625, ack 206, win 261, options [nop,nop,TS val 998507965 ecr 366746071], length 1208 12:27:25.659627 IP6 2607:f8b0:4004:c19::6c.993 > 2607:f3e0::12.56498: Flags [P.], seq 3625:4227, ack 206, win 261, options [nop,nop,TS val 998507965 ecr 366746071], length 602 12:27:25.659641 IP6 2607:f3e0::12.56498 > 2607:f8b0:4004:c19::6c.993: Flags [.], ack 4227, win 1016, options [nop,nop,TS val 366746100 ecr 998507965], length 0 12:27:25.669774 IP6 2607:f3e0::12.56498 > 2607:f8b0:4004:c19::6c.993: Flags [P.], seq 206:332, ack 4227, win 1026, options [nop,nop,TS val 366746110 ecr 998507965], length 126 12:27:25.697747 IP6 2607:f8b0:4004:c19::6c.993 > 2607:f3e0::12.56498: Flags [P.], seq 4227:4517, ack 332, win 261, options [nop,nop,TS val 998508003 ecr 366746110], length 290 12:27:25.705534 IP6 2607:f8b0:4004:c19::6c.993 > 2607:f3e0::12.56498: Flags [P.], seq 4517:4613, ack 332, win 261, options [nop,nop,TS val 998508011 ecr 366746110], length 96 12:27:25.705550 IP6 2607:f3e0::12.56498 > 2607:f8b0:4004:c19::6c.993: Flags [.], ack 4613, win 1024, options [nop,nop,TS val 366746146 ecr 998508003], length 0 12:27:25.705945 IP6 2607:f3e0::12.56498 > 2607:f8b0:4004:c19::6c.993: Flags [P.], seq 332:408, ack 4613, win 1026, options [nop,nop,TS val 366746146 ecr 998508003], length 76 12:27:25.738466 IP6 2607:f8b0:4004:c19::6c.993 > 2607:f3e0::12.56498: Flags [.], ack 408, win 261, options [nop,nop,TS val 998508044 ecr 366746146], length 0 12:27:57.854752 IP6 2607:f8b0:4004:c19::6c.993 > 2607:f3e0::12.56498: Flags [P.], seq 4613:4911, ack 408, win 261, options [nop,nop,TS val 998540161 ecr 366746146], length 298 12:27:57.855295 IP6 2607:f3e0::12.56498 > 2607:f8b0:4004:c19::6c.993: Flags [P.], seq 408:453, ack 4911, win 1026, options [nop,nop,TS val 366778296 ecr 998
