[RndTbl] weird mts latency issue?

[Trevor Cordes]

Just now on a box I manage I'm seeing weird ping times on a DSL (home) 
connection.  It's wreaking havoc with things.

Has anyone seen a pattern like this before?

on the dsl box out to another IP:
: icmp_seq=1 ttl=56 time=3073 ms
: icmp_seq=2 ttl=56 time=2112 ms
: icmp_seq=3 ttl=56 time=1154 ms
: icmp_seq=4 ttl=56 time=192 ms
: icmp_seq=5 ttl=56 time=3578 ms
: icmp_seq=6 ttl=56 time=2616 ms
: icmp_seq=7 ttl=56 time=1658 ms
: icmp_seq=8 ttl=56 time=694 ms
: icmp_seq=9 ttl=56 time=4125 ms
: icmp_seq=10 ttl=56 time=3170 ms
: icmp_seq=11 ttl=56 time=2202 ms
: icmp_seq=12 ttl=56 time=1240 ms
: icmp_seq=13 ttl=56 time=289 ms

It's bursty, the above is 3 bursts, where I start the ping, wait 3s and it 
spits out 4 replies together, then again... sometimes the time is up to 
10kms.

If I ping from my box to that box I get even more weirdness:

 icmp_seq=1 ttl=57 time=60.8 ms
 icmp_seq=2 ttl=57 time=60.0 ms
 icmp_seq=3 ttl=57 time=61.4 ms
 icmp_seq=4 ttl=57 time=70.4 ms
 icmp_seq=1 ttl=57 time=3612 ms (DUP!)
 icmp_seq=2 ttl=57 time=2649 ms (DUP!)
 icmp_seq=3 ttl=57 time=1692 ms (DUP!)
 icmp_seq=4 ttl=57 time=726 ms (DUP!)
 icmp_seq=5 ttl=57 time=63.4 ms
 icmp_seq=6 ttl=57 time=59.3 ms
 icmp_seq=7 ttl=57 time=62.4 ms
 icmp_seq=8 ttl=57 time=68.3 ms
 icmp_seq=9 ttl=57 time=61.4 ms
 icmp_seq=5 ttl=57 time=4366 ms (DUP!)
 icmp_seq=6 ttl=57 time=3403 ms (DUP!)
 icmp_seq=7 ttl=57 time=2443 ms (DUP!)
 icmp_seq=8 ttl=57 time=1488 ms (DUP!)
 icmp_seq=9 ttl=57 time=518 ms (DUP!)

I don't think I've ever seen DSL behave that strangely...
