A big fail to our community, for up to this day, not
implementing basic routing and forwarding filters that would
do away with all this cruft in the first place.
Clearly the Youtube/Pakistan/PCCW incident has long been

The fact that the hijacking ISP's upstreams accepted routes
through their network that didn't belong to that ISP is bad
enough.

Another interesting thing that I noticed, is that AS33611 is not
advertising any prefixes other than yours. Either they do not have any of
their own (unlikely)
or they are advertising their own legitimate prefixes from another AS
however I doubt that is the case. It sounds like you were able to v
The interesting thing is that I'm not seeing any new "hosts" from those

I would go at first by advertising your prefixes as a /24 as well, just
randomly checked 2 different locations and the as-path to 11325 is shorter
than to 33611
This seems to be the case for customers of Tiscali and L3, so this will
probably get most of your traffic back to you...

To be honest I haven't had much success it convincing a tier 1 to

33611 looks like they get transit from 19181, who's only upstream appears to be

If you both announce a /24, the BGP route selection process should begin to
return some of the traffic to these prefixes back to your AS.
Also, if you begin to advertise your prefixes as /24s and as a result, they
try to advertise /25s, I would venture a guess that their /25s would
get blocked enti
I can routes are wrong for all /24 annoucements.
May be contacting Level3+Telia+AboveNet+Hurricane Electric since all these
are upstream providers of AS29791 which is your upstream carrier? I guess
they would be able to neutralize effect significantly by filtering those
routes?

Surely something is better than nothing. Advertise the /24's and the
/25's, see what happens.
At the least it's a step forwards until you get their routes filtered.

Most large transits and NSPs filter out prefixes more specific than a /24.
Conventionally, at least in my experience, /24's are the most-specific
prefix you can

Some will accept it but not propagate it upstream. This may be useful in
re
Upstream requirements. Additionally, I don't believe it would do us any
good. If they're announcing /24 now, why would they not announce a /25.

You can break your blocks into /24's or smaller and readvertise them to
your upstreams. You can also modify local preference using community tags
with most upstreams. If you have tier 1 peerings you may be able to get
them to filter the bad routes if you can prove they were assigned to you by
ARI
Many/most transit providers filter prefixes longer than /24, so the
effectiveness may be minimal.
At the very least I'd advertise /24s yourself because if the forger is
geographically further away, some local sites may still work. Better than
nothing.
