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".

This one I see.
These are coming from UUNET -at least as seen from here -
AS 705 added 4426 prefixes (from 609).
As there was not a corresponding increase in address space,
this is really more of a de-aggragation.
Same thing happened on Wed Apr 24 06:12:20, when
AS 701 added 2364 prefixes (from 2053). Again, it looked
like a de-aggragation.
If you look at Figure 1b of
http://www.multicasttech.com/status/index.html
you can clearly see both jumps.
AS 705 has only one ASN in transit through it from here.
The recent change was all _inside_ AS 705.

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

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:

THe file is 0.5Mb so I couldnt really email it

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:
(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.

URL Seems unreachable (might be because there was a top level domain omitted

Sorry, not enough sleep last night. Here's the corrected URL, with the
added bonus of stripping out some of the unnecessary goo:

UUNET has "re-absorbed" 6869 routes and everything seems back to
normal here.
