Routing health

AS28512 announces 72 IPv4 and 43 IPv6 prefixes.
12 of 115 announced prefixes are RPKI invalid: 189.202.112.0/24, 189.202.113.0/24, 189.202.114.0/24, 189.202.115.0/24, 189.202.116.0/24 (+7).
72 of 115 announced prefixes are RPKI valid.
31 announced prefixes are not covered by a ROA of AS28512 (they may have none, or another network’s).
One upstream or peer seen (AS28545): an outage there takes the whole network off the internet.

For every check with the fix (IRR route objects, the RPKI state of each route, reverse DNS and the registration), run the full network report.
