I've got AT&T Fiber's 5 gigabit symmetric service (with a Ubiquiti equipment stack that handles 40 gigabit without issue) and while its been very stable and I win all nerd fights with my speed tests, I've been thinking about dropping back down to 1 gigabit because I don't find much value out of 5. If it was cheaper ($180/mo for 5 gigabit) maybe I'd keep it but Astound/WaveG is offering gigabit symmetric for $50/mo with 4 free months so tough to swallow.

How many hours can you saturate that 25 Gbit connection up and down before support calls you and tells you to knock it off?

I ran about 8TB on my fiber in one month, and no ISP notices to speak of. That's only ~25mbps sustained. You could easily push 500+TB on a 25gbps connection if you were doing something naughty with it, and I'm sure you'd hear from them about it if you did!

Recently moved up to 3gbps bidirectional and had a hell of a time getting 3gbps even with 10gbps network card directly into the 10gbps port on the ISP-provided modem. In addition to this, there are very few services that will actually feed you data at 3gbps. Steam - ~280MB/s (2.2gbps) Battle.net launcher - ~140MB/s (1.1gbps) 25GB Torrent with 1000+ seeders - ~70MB/s (~560mbps) 2GB iso from github - ~80MB/s (~650mbps)…

280MB/s steam? On a good day I get 25MB/s (Vodafone 400/25) on any German mirror

For home runs I'd recommend using duplex instead of simplex (the cable out to the provider has to stay to whatever they require of course). For a 100M cable it's $37.47 for the duplex and $24.48 for the simplex, the price difference of $13 for a really long run. The price difference of 2x 25BASE-LR (duplex) vs 2x 25BASE-BX (simplex) transceivers will be more like $60. Even if you want to stick with simplex optics everywhere adding If your concern is the physical size of the cable just make sure you're getting a non-splittable duplex cable. Some people prefer splittable because then if they need a simplex cable they can just pull it apart but that's what requires the cable to be larger as you get 2 individually shielded cables. The actual fiber core is measured in microns, you can pack 100s in roughly the same sized jacket.

Bonus note: If you're ever looking at doing a bunch of runs between two spots you can look into MTP/MPO trunk cables. These put 12 strands in the same protective sheath so it's still a really tiny cable and then you can break out via a pigtail cable at the other end.

And here I am with 300Mbps (Charter/Spectrum) that tanks to 50Mbps after 5:00 PM for the "low" price of $99.99/month...

Speeds seem to vary based on the game and based on releases, interestingly. Some larger new-releases (Baldur's gate) were only hitting Aside from that release, almost everything that is a good size (>10GB) has gotten north of 100MB/s pretty regularly.

I used 2TB on my cable modem once and got called with them trying to upsell me to Unlimited data for $75/mo more.

Yeah, that is also what I found. 'Just' 1gbs fiber, but downloads are often bottlenecked by the server, especially things like GitHub.

You absolutely should not ever get hassled for using a product that you already paid for, that's incredibly stupid. Unfortunately the US just treats anything that isn't a corporation like trash.
