peer routing issue between SBC and SPRINT in DFW??

Wed Nov 26 23:51:36 UTC 2003

Hi John,

I just chatted with someone in the SBCIS NRC and discovered the situation 
has been resolved.  There was a loop in Dallas and they did escalate 
properly & resolved it within an hour of notification.  Not bad for 6 pm on 
the eve of a national holiday <G>

BTW, http://www.sbcbackbone.net is working, confirmed from three other peer 
networks.

Enjoy your turkey day tomorrow!  Cheers, -ren
