Inconsistent slow downloads from nodejs.org

[broksonic21]

I am not sure if nodejs/build is the right place to file, so feel free to move

When trying to download a nodejs version, we usually are very fast. We see similar speeds from our CI servers, local, etc across multiple networks

Example:

> curl https://nodejs.org/dist/v20.16.0/node-v20.16.0-linux-x64.tar.gz --output a.tar.gz

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100 44.5M  100 44.5M    0     0  10.7M      0  0:00:04  0:00:04 --:--:-- 10.7M

However, at random times, we get super slow. I can rerun this download 10 times, and 3 will fail with this slowness

it's not a local network issue, as this is happening across multiple networks and people, and appears worse over the last 3 days.

Any insight or additional info I can provide support for?

Example - before I killed it 6 minutes in - 152K download:

> curl https://nodejs.org/dist/v20.16.0/node-v20.16.0-linux-x64.tar.gz --output a.tar.gz

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
 87 44.5M   87 38.8M    0     0   102k      0  0:07:27  0:06:30  0:00:57  152k^C

Realized nodejs.org might be a better fit, so also filed here: #3898 sorry for double ticket. I know when there were 500 errors at Fastly, the fix was somewhere in the middle, so not sure which team this is.
