This is more w.r.t. the huge burst of announcements yesterday, not a persistent increase in the routing table sizes, but.. We saw absolutely huge amounts of announcements from 1 3459 17676 (sometimes with padding) For example, see: http://ginseng/bgpview.cgi?time=between&start=2002-05-01+06%3A00%3A00&end=2002-05-01+07%3A00%3A00&bins=100&prefix=&rel=eq&aspath=&asrel=contain&origin_as=17676&scale=linear&table=updates_new&action=plot&View=View (Sorry for the long URL). Shows that we received something like 30k announcements that originated from 17676 between 6 and 7 am on May 1st. They were primarily announcing /23s out of large address space ranges allocated to APNIC, like 219.31/16 and friends. -Dave On Thu, May 02, 2002 at 11:33:50AM +0100, Stephen J. Wilcox mooed:
We see that too
Predominantly seems to be massive amounts of /24s in a couple of nets which were previously /16s. Culprit would appear to be AS705
*>i63.0.0.0/24 62.24.196.1 100 0 286 209 701 705 i *>i63.1.0.0/24 62.24.196.1 100 0 286 209 701 705 i *>i63.2.0.0/24 62.24.196.1 100 0 286 209 701 705 i .....
Lots of new /20-24 in 67.0.0.0/8 also AS705
In total AS705 is announcing 4432 new routes from yesterday.
If you're interested a copy of all new routes since yesterday is at:

Around 15mins ago an additional ~5,000 routes entered the global view, sadly they appear to be hanging around.
Last Tuesday had an increase of 2,000 routes.
+7000 routes in a week is significant de-aggregation or leak, any ideas on where these routes are flowing ?
I've not seen an increase on any of our peers, so I can only assume its coming from a network who doesn't peer particularly "openly".
