Network meltdowns anywhere in US?

Hi, Sorry, would have posted this elsewhere, but I can't get to alot of places... I originally started chasing not being able to get to 71.74.56.243 (RR Mail server). I then found out neither L3 nor my other connection saw it in the table. I checked a few other router servers, some had it, some didn't. Now, though, I'm trying to get a few other places and most of them oddly seem to hang off L3.... (Like the outages list. :) ) Any ideas of there is some meltdown happening in L3 or elsewhere? Thanks, Tuc
