Completely unrelated to l'affaire ORBS of course, but in this more
recent example, was uunet kenya a transit customer (or customer of a
customer) of abovenet? And quoting from a previous email -
--------
An interesting bit is that the current announcement on routeviews
directly from AS 6461 has Community 6461:5999 attached:
...
6461
64.125.0.137 from 64.125.0.137 (64.125.0.137)
Origin IGP, metric 0, localpref 100, valid, external, best
Community: 6461:5999
...
According to this, that community is used for "internal prefixes":
http://onesc.net/communities/as6461/
"6461:5999 internal prefix"
A "sh ip bgp community 6461:5999" currently yields 130 prefixes
with Origin AS of 6461 and that community. Nothing more specific
than a /24, although many many adjacent prefixes that would
presumably be aggregated normally are announced as well.
-------
anybody see similar routing loops for those other prefixes that'd make
it look like 5999 is a blackhole community at abovenet, so this dude
is seeing what ORBS saw way back when (2000, right) - that is, he had
abuse issues, was downstream of a downstream of abovenet and got his
/24 blackholed?
