Woefully outdated Verizon & Lumen ARIN whois/SWIP data

[na...@jima.us]

Hi all,



I apologize for dredging up the topic on this forum, but 
Lumen/CenturyLink/Qwest/US West has been continually unable to help me despite 
multiple attempts over years (yes, years), and Verizon's response to my 
colleague was to blame a downstream consumer of the whois data (?), and to use 
the opportunity to try to sell value-added services as a prerequisite to 
escalating the matter (!?).



Does anyone have a lead on someone within those organizations who understands 
how to delete IP space assignments?



Thanks in advance!

***Broadband outage limits internet access across the region***
A major broadband outage has forced the suspension of online classes, limiting 
internet access and other mobile services across the country and further up the 
Caribbean region.
Two of the country’s main service providers—FLOW and Digicel—have been severely 
impacted by a major ‘fibre fault” on an underground cable. Because of this, 
customers will experience challenges browsing the internet, loading emails, 
sending and receiving WhatsApp messages and making landline calls.
People have reported difficulty using internet services from all corners of the 
country. There are also reports that some schools have been forced to suspend 
online classes because of a lack of internet access.
A broken underwater fibre cable between Antigua and Guadeloupe is suspected to 
be the reason for the outage. A statement by Cable & Wireless Communications 
(CWC) stated:
“CWC advises of a possible fibre fault between Antigua and Guadeloupe on the 
Xtera-Optima, ECFS.”
Digicel customers in Barbados and St. Vincent are also affected by the outage.
Sources at FLOW stated it could take some time before services are fully 
restored. Information from the company’s network operations centre estimate 
full repair will be completed by Thursday, because damage to the underwater 
cables appears to be “major”. They indicated that a temporary solution is 
currently being put in place. While internet will return, customers are likely 
expected to encounter unstable connections with dropouts until the situation is 
rectified.
Digicel posted an advisory to its Facebook page a short while ago.
“Valued customer,
We are aware that some of you may be experiencing an outage with your internet 
services. Preliminary investigations indicate that the cause is a technical 
issue with our international upstream internet suppliers which is affecting 
multiple internet providers across T and the Caribbean.”

Re: Apple Catalina Appears to Introduce Massive Jitter - SOLVED! - Update!

FWIW, in this really interesting read

about
the latest vulnerability released by Project Zero, they talk about AWDL and
how if this is in use (AirDrop enabled?) then you're going to get tons of
jitter/packet loss.
