ARIN contact needed: something bad happens with legacy IPv4 block's reverse delegations

[Eygene Ryabinkin <rea+nanog () grid kiae ru>]

We (at Kurchatov Insitute) still use 144.206.0.0/16, the legacy
block, and seeing the breakage rooted at ARIN since this night,

Seems like the other /16 from 144.in-addr.arpa are affected too
(at least).

ARIN tickets are engaged, but I am seeking some live person:
having the whole reverse zone being unavailable isn't the stuff
that is to be handled in 5x8 or alike.

If anybody knows what happened, can point me to my errors
in assertions or give an e-mail/phone of 24x7-like person
or service at ARIN -- will be tremendous.

Thanks!
