[No attempts at 01-April humor will be attempted in this message.] Seeking help from routing engineers around the 'net: ARIN documents that 192.139.135.0/24 has been allocated to Metro Wireless International: https://whois.arin.net/rest/net/NET-192-139-135-0-1 Further, the party to whom 192.139.135.0/24 has been allocated has published a ROA in ARIN's hosted RPKI asserting that bgp announcements for that prefix are valid only when originating in AS63251. To view this, go to your favorite RPKI vantage point that uses ARIN's TAL.
