Hi,

the tables bellow show the number of IPv4 and IPv6 blocks per AS that are 
unreachable in an RPKI
route origin validating (ROV) environment (this list is filtered for UK ASNs).
(data as of 2018-09-26 12:51 UTC).

Affected networks might soon (by the end of the year) loose the ability to talk 
to
Cloudflare networks since they plan to deploy ROV.

I'd encourage everyone to look into the ROAs of affected prefixes
(or to ask their customer / responsible IP holder to do that).

You can use the RPKI validator https://rpki-validator.ripe.net/bgp-preview
or https://bgp.he.net (prefix view) to find the specific affected prefixes
for a given ASN.

The RIPE RPKI dashboard offers a notification service for these kinds of 
problems
and every operator should use it to get automatic alerts and avoid reduced 
reachability.

If the invalids are expected (i.e. to test ROV)
than you can ignore this email (and maybe drop me an email).
