Last night, I could not load centos.org in my web browser. At this time, I can load centos.org in my browser, without problems. Below are the results of 3 tests.

[lanny at dell2400 ~]$ Test #3 When I run the command "mtr -c 10 -r centos.org" I continue to see the line which includes "???" and "100% loss" within the Layered Tech DC in Dallas.
