Coherent 100G in QSFP28
by Jared Brown 28 Feb '23

28 Feb '23

Looks like coherent 100G in the QSFP28 form factor is finally on the horizon. From the datasheet: * 100G coherent DWDM in QSFP28 form factor * tunable, flexible grid * 300 km with amplification, 120 km without * industrial or commercial temperature * 5 watts https://www.adva.com/en/products/open-optical-transport/pluggables-and-subs… - Jared

Re: Upstream bandwidth usage
by Mel Beckman 27 Feb '23

Adam, Your point on asymmetrical technologies is excellent. But you may not be aware that residential optical fiber is also asymmetrical. For example, GPON, the latest ITU specified PON standard, and the most widely deployed, calls for a 2.4 Gbps downstream and a 1.25 Gbps upstream optical line rate. -mel > On Jun 9, 2022, at 3:08 PM, Adam Thompson <athompson(a)merlin.mb.ca> wrote: > However, if you're talking about fiber service, it's pretty much pure marketing-dept-driven BS, combined with some vague justification of not letting TOR nodes or copyright-ignoring seeders/Warez-providers/etc. overwhelm the network in unexpected ways.

Any Wave/Astound clue on the list?
by Mike Lyon 22 Feb '23

22 Feb '23

Going on 12 hours on an outage that is due to a power outage somewhere. According to the Wave/Astound NOC, generator(s) were on the way 6 hours ago… If you could hit me up offlist, i can give you the master ticket number. I’m having a hard time figuring out why it takes 6 hours to get a generator up and running in Silicon Valley. Thank you in advance for any help. -Mike

Last undersea Internet cable connecting Vietnam with the world breaks down
by Sean Donelan 22 Feb '23

22 Feb '23

https://en.vietnamplus.vn/last-undersea-internet-cable-connecting-vietnam-w… Since February 10 when telecommunication firms took technical solutions and opened up more data flows on land-based cables, the Internet connections have been improved and 50% of international Internet capacity has been restored. Nguyen Hong Thang, Director of the Vietnam Telecommunications Authority, said that a coordination board was established to monitor measures responding to the submarine cable incident. Notably, besides applying technical measures, telecommunications firms also quickly opened more connection capacity on land cables to ensure service quality and interests for Internet users despite high costs, he said.

Cloudflare contact?
by John Von Essen 20 Feb '23

20 Feb '23

I work with DuckDuckGo, and earlier today our macOS browser (which is currently available via the App store now) started getting caught by Cloudflare’s bot/fraud system. We did a fair amount of debugging, it appears to be some kind of browser/UA fingerprinting. This is happening for pretty much anyone using our browser, anywhere in the world, when browsing cloudflare powered sites. My hunch is this is accidental, but since we have no direct contacts at Cloudflare, we’re having a hard time escalating this. Thanks John
