Hi,

It’s been a long while since I first used Mojo (wrote conway’s life via the playground a while back).

Today I downloaded the Mojo compiler using Pixi and test ran the hello world once again.

**Hats off to the team, this was really smooth experience.**

During the compilation, I noticed that the compiler process would attempt to make a network call. Of course, it worked fine without being able to access it.

I’m just curious if this is being used for telemetry or for other metadata updates?

That’s great! thanks for sharing ❤

As for the network call, it’s for telemetry which can be disabled via `MODULAR_TELEMETRY_ENABLED=0`.
