Our Scaleway instances are taking tens of minutes to download 7 MB:

It's painfully slow.

Maybe we need to cache harder and mirror the buildlet in Paris or in their object store.

But that doesn't help if we have to push 40 MB of source at each build.

This bug is about investigating where Scaleway networking is slow.

In the meantime we need to disable our linux-arm trybots.
