100Tbps downloads speeds (5Mbps upload)

Speeds not guaranteed...

[–] runefehay@kbin.social 3 points 6 months ago

Isn't the phrase they use "up to" the promised speed? So if it is 300bps, that is not above 5Mbps, so they technically met their promise.

Aren't fiber lines typically symmetrical? At least that's how I've usually seen them advertised.

You underestimate the fuckery that ISPs will go through to offer the least amount of services for the most possible money.

Mine at least lets me adjust the upload and download ratio for my plan. I'm currently on 50/20, but I could upgrade my plan and get 100/20, 70/50, or whatever I want. But 50/20 has been plenty for me, and we're getting municipal fiber soon so I'll have more options as well.

AFAIK, cable doesn't offer that, you get 5mbps on pretty much every plan, or you upgrade to some ridiculous tier to get faster upload.

5Mbps is absolutely bonkers. I had 30/5 back in like 2006. And TCP has an overhead of about 5%, some protocols ever more.

I lost my symmetric gigabit fiber recently after moving and I miss it dearly. Might have upgraded to 3Gbps by now 😭

I had gigabit a long time ago, and while it was nice, I'm unwilling to pay for it. 50/25 is good enough for me, and it costs less than half what gigabit would cost ($55/month vs $125/month). I just checked, and apparently all plans have half the upload vs download, so that's nice.

Our new service promises to be $60-70 for 250 symmetric, and that would only get me 100/50 at my current ISP, so I'll probably be getting that upgrade when it's available.
