It's cool how the fire code used to be "yeah just punch a hole in the drywall if you want". It's like there was a shortage of saws or something.

There's a great video where some massive exchange in NYC (maybe) got burned out and due to the size of the company and the fact they were also the manufacturer they pulled in people from all over the country, diverted hardware that was due to go out to other areas and adapted it for the rebuild, expedited cable manufacturing, dragged in trailers of payphones etc. and had everything up in a couple of weeks. Not sure you could do that now where everything is a contract with a third party. E: This one https://www.youtube.com/watch?v=f_AWAmGi-g8

Lot of juice in those systems to provide the ring.

Wasnt that one of the original push backs to VOIP? That regular copper lines still had enough juice in them to work during power outages and stuff? Old telephony is just so interesting to read about, but Im glad I dont have to work with it. Though I am old enough to have used a butt set and done some work with the old POTS stuff.

A lot of critical stuff still uses copper lines, or has them as a fallback, precisely because they’re so reliable. Copper trunks going down is so much rarer than internet service or PRI or SIP circuits going down and with a good UPS you can keep some plain digital (not IP) phones going pretty easily through a power outage. I’ve worked on stuff like a mental health support line call centre system, and yeah, they’re not about to trust a SIP trunk (especially from our local provider…), they’ve got a dozen copper POTS trunks in a hunt group. And they have contingency plans in place to reroute calls to a different physical location. You’ll occasionally get a copper trunk fail or degrade but that usually happens slowly a pair at a time. I’ve been doing telephony stuff in my current job for >6 years and I’ve seen SIP and PRI trunks go down all the time but the only occasion I can remember where anyone with normal landlines had total loss of service was that time when a city work crew repairing a burst water main took a backhoe through the main backbone between two of the main local telecom exchanges.

I believe I read that Verizon is abandoning their copper infrastructure around here and putting in FIOS. I don't like it, I like that emergency phones used to work during power outages, but I guess regulators didn't care enough.

UPSes that are monitored and tested gets you around the power loss issue, and for life-critical services you use diversely routed fibre so that digging one route up doesn't cause a problem. There's no inherent reason why POTS needs to be more reliable than IP, I think people are just used to paying telephone line rental money and getting something incredibly robust as a result, even if a lot of that is by accident rather than anything that the phone company promises.

In the UK, copper has been declared obsolete and is being replaced, and they no longer do analogue-only phones or DSL. Fibre for all!* * except, you know, where it's the slightest effort.

I can't imagine the hell that is losing your copper internet and being forced onto 5G. Fiber's great and all but copper is still perfectly viable.

They had two data centres, once in the same building and one in Osaka. There were two network links to Osaka, and the vendors were specifically chosen so that one routed left out of the building and up the street, and one routed right out of the building and down the street; as well as one going along the Pacific coast and one going along the spine of the island.

I think I told this story before byt at my old radio job, one day we came into the office and none of the phones or internet worked, which was an issue because that's how radio works these days, even in the 2010s. It turns out GTE/Frontier sold off our entire bank of numbers without realizing they were actually connected to accounts that had been there for 60 years. Telecoms, man

Today I learned that my department is the #2 fastest in the entire company in ticket times. ... This is because 95% of the tickets assigned to us are done so incorrectly so it lives in our queue for only a minute or so before we angrily send it back.

Very likely that is the case, but the point is that people should not add random IP addresses they have no idea who they belong to for testing. To clarify, because it's not apparent from the previous post, "add" in this case refers to whitelist.

Well last I checked they used them internally across a million different segmented networks so it would be a huge shitshow for the DoD if they started peeling them off for public use. I’m guessing. Or not. You can use whatever you want internally tbh there aren’t internal IP CIDR police that are going to come and arrest you. Might gently caress your stuff up though depending on what it’s overlapping with

I have no idea how likely such a scenario is, but there sure were a lot of people confident that 1.x.x.x was going to remain unused forever too. wolrah fucked around with this message at 15:19 on Jul 6, 2023 |

My son’s friend bought a new computer with his hard-earned money and the tried to downgrade from windows 11 to windows 10 so he could play games. Of course the downgrade screwed everything up and in a moment of weakness I said I’d flatten it and install win 10 from scratch. It runs much faster but now it has a hard crash and reboot that I’ve been troubleshooting for weeks now on an on-again off-again basis. It kills me that this kid paid $1300 for a kick rear end PC that has some kind of issue that I cannot resolve and I’m bummed for him and annoyed at myself for taking this on. Stupid computers. Stupid Agrikk.
