I'm seeing the same thing from my edge routers in Toronto and New York but
am discarding the route on each due to it being RPKI invalid. Looks like a
potential hijack by a Russian ISP based on the origin ASN.

NLNOG RING also shows some of their peers accepting the invalid
announcement while others are accepting the correct one.
