AT&T FTTH in Texas. Its 2-3ms from my home to Google's CDNs. 2-3ms to Cloudfront. 4ms to akamai. Its 3ms to my friend's house, 1ms to my work's office. Its 2ms to my colo in town.

40ms is me essentially connecting halfway across the country. A Digital Ocean droplet in SF or NY is ~40ms.

How are you measuring this? Because I just ran a ping from my colo server in a datacenter and am seeing 11-12 ms when I ping google CDN.

All of this was measured on my residential FTTH internet from a wired desktop just using the Windows ping utility.

11-12ms to a Google CDN from your colo? That's insane to me. Pinging from my colo to Google using the ping utility from iputils for 50 packets gives an average ping of 1.6ms. Akamai pings at 2.1ms.

Ok, so I ran a ping again from my data center server. And for CDN.google.com, I get average of less than 0.2ms ping. But, when pinging www.gstatic.com, that is when I get more like 7-10ms.

I'm not sure what the difference is between the two.

Depends on where you live and where you measure to. Generally, it's fair to measure to the first IP hop, if you live far from any major internet exchange, that's going to add to your latency regardless.

I've seen fast-mode DSL around 7ms, interleaved DSL around 20 ms, cable usually 5-10 ms, but highly variable. ATT GPON was 5 ms which I thought was pretty high, although fiber should really be sub 1 ms.

I've seen LTE between 10 and 60 ms (or worse, when it's congested), older technologies are usually quite a bit more.

How are you measuring? Everyone is saying they get such low latency, I just ran a ping to 8.8.8.8 and get the following on my colo server in a Las Vegas data center:

PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data. 64 bytes from 8.8.8.8: icmp_seq=1 ttl=115 time=12.7 ms 64 bytes from 8.8.8.8: icmp_seq=2 ttl=115 time=11.4 ms 64 bytes from 8.8.8.8: icmp_seq=3 ttl=115 time=10.6 ms 64 bytes from 8.8.8.8: icmp_seq=4 ttl=115 time=10.9 ms

I get about the same from my home cable internet connection.

I am on Google Fiber and I get < 10 ms to anything served out of a CDN or to servers in my own state. If I ping google, reddit, amazon, etc they are all about 8 ms.

Our rural fixed wireless has 5-10ms jitter, but 14ms (up to 25ish ms cause jitter) is easily observed when pinging CloudFlare via the KCIX exchange (where our ISP sends most of it's traffic).

Just ran a speedtest on my phone; I get 19ms on a Farmer's Telecom fiber. 60-70ms on the work VPN.

The last time I had >20ms RTT "Fast Path ADSL" was still a thing.
