This is to inform everyone that routing between the US and most 
UK networks (along with several other European networks) will
transition from the NASA Science Internet (NSI) to the Sprint/ICMnet 
today (Wed, Oct. 13) at noon EDT. There will be about a 10-15 min
interruption in service while the multiplexers and routers are 
reconfigured. The trans-Atlantic link speed will remain at 1.024Mb.

There are a total of 475 networks which will be affected by this
change. The new primary path will be via AS 1800. A complete list 
of the networks involved is available via anonymous ftp from 

Thanks to Merit and Sprint for making this easy. If there are 
any questions or problems, please send me mail.
