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. If
you don't yet have a favorite, feel free to telnet to
route-server.ip.att.net and run:
show validation database record 192.139.135.0/24
Unfortunately, as may be seen at route-views, etc, most of the
Internet now prefers an invalid path that's mis-originated in as4808:

Please help the Metro Wireless International folks get this cleared up
so their 192.139.135.0/24 can once again be usable. In particular,
help is sought from 4837 and their transit providers:
1239
701
3356
(Yes, I am trying to reach folks at those networks in other ways, too.)
Thanks.
Jay B.
