The last couple of days, I've been having problems with interactive ssh into login.tools.wmflabs.org http://login.tools.wmflabs.org/. Every so often (multiple times an hour, at least), my connection will hang for a few seconds. Sometimes more like 10-15 seconds. I connect from my home MacOS box on broadband using:
ssh -t -i ~/.ssh/id_rsa_wikimedia roysmith@login.tools.wmflabs.org tmux attach -t work
The load doesn't look unreasonable:
$ uptime 18:26:34 up 35 days, 9:04, 39 users, load average: 0.74, 1.93, 1.80
and ping times look fine:
$ ping -v login.tools.wmflabs.org PING login.tools.wmflabs.org (185.15.56.48): 56 data bytes 64 bytes from 185.15.56.48: icmp_seq=0 ttl=51 time=24.233 ms 64 bytes from 185.15.56.48: icmp_seq=1 ttl=51 time=27.086 ms 64 bytes from 185.15.56.48: icmp_seq=2 ttl=51 time=22.121 ms 64 bytes from 185.15.56.48: icmp_seq=3 ttl=51 time=22.726 ms 64 bytes from 185.15.56.48: icmp_seq=4 ttl=51 time=24.497 ms 64 bytes from 185.15.56.48: icmp_seq=5 ttl=51 time=24.809 ms 64 bytes from 185.15.56.48: icmp_seq=6 ttl=51 time=23.913 ms 64 bytes from 185.15.56.48: icmp_seq=7 ttl=51 time=25.811 ms 64 bytes from 185.15.56.48: icmp_seq=8 ttl=51 time=25.266 ms 64 bytes from 185.15.56.48: icmp_seq=9 ttl=51 time=22.865 ms 64 bytes from 185.15.56.48: icmp_seq=10 ttl=51 time=32.076 ms 64 bytes from 185.15.56.48: icmp_seq=11 ttl=51 time=26.069 ms 64 bytes from 185.15.56.48: icmp_seq=12 ttl=51 time=27.947 ms 64 bytes from 185.15.56.48: icmp_seq=13 ttl=51 time=27.088 ms ^C --- login.tools.wmflabs.org ping statistics --- 14 packets transmitted, 14 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 22.121/25.465/32.076/2.484 ms
I'm in New York City, and login.tools.wmflabs.org http://login.tools.wmflabs.org/ looks like it's in Virginia, so that's pretty close.
This seems to have started in the past few days. Anybody else seeing problems?
