Looks like level3 is having issues. Anyone know what is going on?

It seems anything traversing level3 has very high latency along with what seems overloaded capacity as if they are running in a degraded mode I have connections with Time Warner, AT&T, and MCI. Though I know it is not concrete it seems as if something is going on according to this http://www.internetpulse.net/

| Seems to be all cleared up now. I had a couple of my customers even try to pull up their home site and could not get to it.
For FYI  I realize that ICMP is not the best way to test and it is not a true indication of slowness or the presence of a problem.

Uhh, you do realize the end to end latency there (to hop 12,
at least)
is ~30ms...not the 250ms+ you see on intermediate hops,
right?

Yes sir I did. This is now resolved. But thank you for noticing.

Which begs the same question I've asked in the recent past:
then
what *is* a good diagnostic tool? If ICMP "is not the
best way to
test", then what is? What other globally-implemented
layer 3 or
below protocols do we have available for troubleshooting?
Sure, UDP-based traceroute still relies on ICMP TTL exceeded
responses to work. I've no idea what TCP traceroute relies
on,
as I haven't looked at it.
