Level3 transit issues in NE?

Hey everyone, We've been seeing reachability issues to prefixes on Level3's network since early this morning. Paths that take L3 via XO seem to be displaying the same problems. Our Level3 peer is in Philadelphia, XO peer is in NYC. We have not been able to get a call back from Level3 since 5am. Has anyone heard any info regarding this? -- Ross Vandegrift ross@kallisti.us "The good Christian should beware of mathematicians, and all those who make empty prophecies. The danger already exists that the mathematicians have made a covenant with the devil to darken the spirit and to confine man in the bonds of Hell." --St. Augustine, De Genesi ad Litteram, Book II, xviii, 37
