The only fiber cable between Finland and Germany has suffered a cut last night. The cable mostly follows the Nord Stream routing in the bottom of the baltic sea.

The remaining links are mostly via Sweden.

I would expect this to hurt Hetzner the worst, since a lot of the workloads they host in Finland are here just for the cheap electricity but are actually connecting with clients elsewhere.

Must be weeks rather than days before this is fixed

With the latest Bezos fuckery it’s a good time to commit to finally getting our AWS spend down to zero.

We’re about two thirds of the way there but still paying AWS more than $3,000/month—three grand more than anyone should

@chaz @ryanc @kajer 10km LR optics are also safe without attenuators.

I ran OS2 fiber in my house badly enough that 2km doesn’t cut it for all the links (and they’re under the floor so not going to get redone any time soon). Luckily I could just brute force the link with a 20km optic just fine 😅🥴

The Network Is The Building™️

@duco @dalias I run a small fiber network and can confirm that in principle there’s very little marginal energy cost to traffic. Our peaks are in the 50–80 gigabits per second range and don’t really show up on router electricity usage graphs compared to the 10x smaller baseline.

That said, wireless is different. Also, much of the capacity is there specifically for video, so it’s not right to look at the marginal cost alone.

Netflix can now serve 100Gbit/s of video (so something like 12,500 individual 4K streams) with an appliance using 100 watts of power. That’s 8 milliwatts for each 4K stream.

Remember that number the next time someone tells you that watching a Netflix show is as bad as driving an SUV or some shit.

@ryanc FS.com reps are generally harmless and occasionally useful, I’m glad to have mine!

The Steam Mac app: still an Intel binary in 2024. But I'm sure they'll keep on top of all platform developments now that they get to make an iOS app store
