this week's cidr progress
This past week's CIDR progress from AS690's point view.

Route table growth: -248 routes (yes, decreased by 248 routes)
Route withdrawn: 704 routes

The following ASs and/or ASs behind them have withdrawn more specific routes during
the period:

AS1324 ANS-NYC-CONNECTION 194
AS701 Alternet 140
AS200 Barrnet 96
AS204 PSCNet 86
AS237 MichNet 72
AS685 NorthWestNet 71
AS1957 ANSCIX 30
AS1800 ICM-Atlantic 6
AS560 NearNet 5
AS1133 CERN/DANTE 2
AS1740 CERFNet 2

New challenges:

There are 1001 routes co-existing with its aggregate in the routing table
currently, that is they can be withdrawn as we speak. ASs who advertise these
nets PLEASE withdrawn them.

EUnet GB (AS1290) is now announcing the aggregate route 193.112/13 and I
have (within the last few minutes) withdrawn the more specific routes from
our external BGP4-capable peers.

Whilst a quite a number of the more specific routes in this block were
not previously being routed I hope that this change has made some
impression on the size of the world's routing tables.

Yup, just checked and saw another 70 some more specific routes covered by
193.112/13 are gone from AS690's routing table. Congratulations!!

There are still several routes covered by your aggregate in the routing
table (see below). You may have policy reasons not to withdraw them, but
just let you know in case.

193.112.16 140.222.41.2 UG (0)0 ffff ff00
193.113 140.222.41.2 UG (0)0 ffff
193.113.58 140.222.41.2 UG (0)0 ffff ff00
193.113.144 140.222.41.2 UG (0)0 ffff ff00
193.114.248 140.222.41.2 UG (0)0 ffff ff00
193.117.15 140.222.41.2 UG (0)0 ffff ff00
193.117.190 140.222.41.2 UG (0)0 ffff ff00

Thanks!
