Ok, I’m not normally one to be the pedantic bits/bytes guy, but if you’re gonna go and make a bit/byte “clarification” you need to get the annotation correct or you'll just confuse everyone.
It’s 500kb (small b for bits) and 62.5kB(capital/big B for bytes).
This is simultaneously fast (on my 14400 bps modem that I spent the most time "waiting for downloading", I was used to 12-13 minutes per megabyte vs. 18 seconds here) and slow (the google homepage is >1MB, so until you have resources cached you're waiting tens of seconds).
It would be nice if everything were just a touch more efficient.
Now, I assume all of this would start working before it's all transferred. But we're still talking about tens of seconds of transfer at 500kbit/sec.
(And Google at least acts like they care about bandwidth a little. So many 15megabyte pages out there...)
We lived for years on 56kbps, granted the Internet was different back then, but we'd still "use" it, download stuff, etc.
Or even better, 62.5KiB (for kibibyte)
Well, we can’t know if Starlink’s marketing team used 2^10 or 10^3, and since it’d inflate their numbers I guess the latter.
So telco rates which are multiples of 56000 or 64000; baud rates which are multiples of 300; ethernet rates which are mostly just powers of 10; etc etc etc.
Of course, there's occasional weird stuff, but usually things have a lot of factors of 5 in there and seem more "decimal-ish" than "binary-ish".
