This means all my searches are very fast, and also means when our main provider (Cogent) is down, we still have access to google and their web caches.

I suspect too that there just might have been a fast link between the google and speedtest datacenters, maybe because google earlier rented part of the other dc. A 3 ms ping looks like it must be from a bay area dc to SFO. They should really do an avg of times/bw to other speedtest nodes in US.
It's not from a dc to the speedtest node; its from the campus. It wouldn't matter anyway. I work at Cisco and I have gigabit link to the core from my laptop. Problem is the speedtest nodes can't push the traffic fast enough to fill the pipe which is something I regularly do when working with campuses in MA and NC.
Now, let’s put these numbers into perspective. According to Ookla’s Net Index, the average speed for a country in Europe is around 12 Mb/second. That's partly because most people are happy with such speeds (or at least the speed/price ratio). At home I have a subscription with 120MBit/s downstream. Speed tests usually give 130MBit/s during daytime and 140MBit/s at night. Given that, 500MBit/s downstream is the very m…

Yeah. I was expecting multi-deca-gigabits at the very least.
The bandwidth each computer has access to is almost certainly not the entire bandwidth that Google gives its employees access to - if so, the per person bandwidth would be quite low. Of course, not being a Google employee, I wouldn't know for sure.
Of course it's fast. They cache the whole thing :)

that sounds like an awesome investment, what are you subscribed too?
300Mbps for about $30 a month. Well, I don't have the best plan, so that will be 100 for ~$20.
Consider that Google is investing in undersea cables [1] which nominally provide multi-terabit speeds between continents. And Google is cheap, really cheap, in terms of what they will pay for infrastructure which is why they started making their own switches [2] because even commodity ethernet vendors weren't cheap enough (although these days of state funded cyber armies one also has to protect against foreign made equipment [4])
What is more the amount of data you can send over a fiber is getting faster all the time [3] so replacing the inter-datacenter lasers can quintuple bandwidth.
There have been some interesting 'escapes' of course, once when one of the data centers became unavailable and all the YouTube traffic started coming from another one very far away serving a very large local population, and latencies went up but throughput didn't change, I know a couple of network administrators did a double take on what they were seeing :-)
