The plan is to decommission TAT-14 in 2024. That is long before the next Biblical Flood due the ice caps melting. The Trans-Atlantic systems have a life span at best of 30 years. When the next set of systems is built rising waters will be taken into account. ________________________________ From: Valdis Kletnieks <valdis@vt.edu> on behalf of valdis.kletnieks@vt.edu <valdis.kletnieks@vt.edu> Sent: Friday, June 2, 2017 8:40 PM To: Christopher Morrow Cc: Rod Beck; nanog@nanog.org Subject: Re: Russian diplomats lingering near fiber optic cables On Fri, 02 Jun 2017 13:23:26 -0400, Christopher Morrow said:
is this a case of 'wherer the cable gets dry' vs 'where the electronics doing cable things lives' ? aren't (normally) the dry equipment locations a bit inland and then have last-mile services from the consortium members headed inland to their respective network pops?
Well, I'd be willing to buy that logic, except the specific buildings called out look pretty damned big for just drying off a cable. For example, this is claimed to be the US landing point for TAT-14 - looks around 4K square feet? http://virtualglobetrotting.com/map/tuckerton-cable-landing-station/view/goo...

Tuckerton Cable Landing Station hosts the TAT-14 fibre cable which runs 15,000km to... Though I admit I'm foggy on how much gear is needed to stuff however many amps at 4,000 volts down the cable core to power the repeaters. But again - if there's gear stuffing that many amps at that many volts down a cable, salt water could be the start of a bad day... (And note - I'm not saying that *everybody* who built a cable landing station managed to get it wrong. I'm saying that with the number of landing stations in existence, the chance that *somebody* got it wrong is probably scarily high. Telco and internet experiences in New Orleans during Katrina and NYC during Sandy suggest there's a lot of infrastructure built with "we never had storm surge in this building before so it can't happen" planning....)
