Yes, CA*NET and the CERN traffic to NSFNET were still on the T1 in November.
We did register some data losses with the T3 traffic-by-network data in 
early November, but I suspect that most of the differences that you noted 
were due to the fact that much of the international traffic did not cross 
the T3 backbone.  Even though the Country report is explicitly labelled as 
representing only the T3 traffic, I can understand the likelihood of 
misinterpretation and have removed the report from  

The upcoming December report should be complete, and I don't expect any
problems.  If you find something that doesn't make sense, please let
me know, and we'll try to track it down.
