I think it does help, in that if the CO stays up a week it's possible DSL over POTS might stay up for that long also. Not certain, but possible. Please warn me if this is a grossly-over-optimistic interpretation.

Many have only a few hours of battery capability, and their battery maintenance is sometimes haphazard. Some larger vaults have built-in or adjacent generators, but many others have only a power plug that connects a portable genset which must be transported, refueled, and safeguarded by mobile power crews that can be thwarted by flooded intersections, downed trees, or theft. Let's face it: the "Alwways on, always works" phone service of my youth has been replaced by "When we feel like it, you're not important enough" compromises that follow economic lines. The only thing keeping many low-profit areas in the power plans at all is the power of the insurance lobby - along with politicians, both in fear of having to actually deliver on their promises.

Payment data remains one of the most sought after and lucrative targets by cybercriminals with 9 out of 10 data breaches being financially motivated, as highlighted by the recent Verizon Business 2020 Data Breach Investigations Report (2020 DBIR). Within the retail sector alone, 99 percent of security incidents analyzed by the 2020 DBIR were focused on acquiring payment data for criminal use. https://www.finextra.com/pressarticle/84386/verizon-reports-sharp-decline-in-pci-compliance -- Bill Horne Telecom Digest Moderator ------------------------------ Message-ID: <86wnzv9l8x.fsf@telecom2018.csail.mit.edu> Date: 12 Oct 2020 21:39:58 +0000 From: Moderator <telecomdigestsubmissions@remove-this.telecom-digest.org> Subject: For Now, Verizon's 5G Home Internet Service Offers Very Little Coverage By Sascha Segan Verizon's 5G Home service may be fast, but very few people can access it-even in the eight cities Verizon purports to serve. Since the company doesn't offer a coverage map for its home service, we pumped more than 400 Chicago and Minneapolis addresses through the Verizon 5G Home address finder, and discovered that the home service has even less coverage than the mobile service does. https://medium.com/pcmag-access/for-now-verizons-5g-home-internet-service-offers-very-little-coverage-a218534c2ed9 -- Bill Horne Telecom Digest Moderator ------------------------------ ********************************************* End of telecom Digest Tue, 13 Oct 2020
