Expected Results

Successful compilation

Having the exact same issue, compiling ESPHome through HomeassistantOS (fresh install) with the 1.14.3 version. Can't ping platformio.org or api.platformio.org.

[jumblies]

I suspect it is almost certainly a server or DNS issue on their side. Naturally, it only happens when I need to compile urgently for a node failure.

[tigattack]

In Home Assistant ESPHome, PlatformIO is pinned to version 4.0.3, which is using hardcoded IP addresses in util.py.
This is in fact _still_ the case in the latest develop branch of PlatformIO - see here.
I discovered this in this issue https://github.com/esphome/issues/issues/1265.

Can anyone answer why on earth hardcoded IPs are being used instead of DNS names?

[jumblies]

Sounds like a dev branch that went into production or maybe they have bought a static IP.

I'm going to close this issue since esphome/issues#1265 has more info

[tigattack]

This has been part of the develop branch for a long time.
Owning a static IP doesn't mean you can't use DNS names, which would solve exactly this sort of issue. Seems like a very poor decision.

While I didn't write it, the code only has to reach at least one of those in order to "pass". Since they've added github.com and platformio.org at the bottom of the list, it _should_ eventually succeed.
