- toast0 4y agoI remember having latency under 100 ms within the metro area, but I could easily be misremembering, and I don't have a PPP account anymore to test. (And I'd have to visit my MIL who has a real POTS line with it's low latency)... But I did find a reference mentioning 150 ms round trips regionally, which I think was US west/east/central, so I think this 150ms is including some intercity latency as well. https://web.archive.org/web/20160305000336/http://www.thefreelibrary.com/TEN+and+Concentric+Forge+Alliance+to+Provide+Fastest+Possible...-a018290454 https://web.archive.org/web/20160305000336/http://www.thefre...
- icedchai 4y agoHmm. Wikipedia is claiming 150 ms latency on dialup: https://en.wikipedia.org/wiki/Dial-up_Internet_access https://en.wikipedia.org/wiki/Dial-up_Internet_access I remember higher, but it's been over 20 years now (we got broadband pretty early here), so who knows.
