The following ASes will disable their sessions with the NSFNET Service
and will reestablish it after a period of time.  These ASes have advised
us that the disabling of their sessions with the NSFNET between 0900
and 1000 EDT on April 21, 1995 will cause reachability and capacity
problems.

Merit has started collecting routing table snapshots from the 
NSFNET Backbone Service and SNMP stats (in/out packets, in/out
bytes), and will continue to do so throughout most of the
day tomorrow.  

If there is a catastrophic failure tomorrow morning, Merit will 
advise the ANS NOC to roll back to the previous configuration (those 
installed Friday morning during the normal configuration window).

If it is determined that problems are isolated to individual autonomous
systems, Merit will enable the sessions with those individual
autonomous systems.

If there are individual routes from many sources which are unreachable,
Merit will designate one emergency configuration time period at
which all of the independent additions will be made.  This time
period will probably be late Friday or early Saturday.

If you are experiencing problems tomorrow after 0900 EDT, please
send mail to merit-ie () merit edu, or trouble () ans noc, or
call 1-800-456-6300.  Merit engineers will be on-call to
address your problems.

Thanks to all of you who have already ceased peering with AS 690,
and to those of you who have worked so hard to meet the April 21, 
1995 deadline.

Hoping not to hear from you tomorrow. :-)
