EuropaNET Migration Starts Tomorrow

You may have heard about the migration of EuropaNET to a new backbone.
Basically, todays core, EMPB (AS 2043) will be replaced by a new core
network, IBDNS (AS 5400). The transition will start tomorrow and hopefully
finish mid next week. The final switch-off of the EMPB is on the 2nd Oct
95, 9:00 CET (GMT+1).

Obviously we try to handle things such that the migration should be smooth.
However, if you are filtering based on AS paths to some of the destinations
below, you might have to change your filters. Generally, if you experience
routing problems during this period to the ASes mentioned below, and in
particular if the core ASes 1128, 2043, 5400 are involved, contact
nmc at dante.org.uk.

For non-European networks these changes should be invisible, except that
some ASes will gradually not use the 1800 1804 1128 connection any more,
but 690 1128 5400 *. This path is in use already today, so there should be
no problems. Note also that a number of ASes mentioned below is not
affected, because they have other arrangements for intercontinental
capacity.

The following ASes are involved in the migration: (This macro as-dante will
be available on whois -h whois.ripe.net tomorrow.)
