Where is https://archives.boost.io/ hosted?

Hi all,
Nicola from the React Native team here,

Over the last ~2 days, the JFrog Boost repository was down/slow-to-respond and caused significant disruption to the whole React Native ecosystem (iOS apps could not build due to failing CocoaPods installation, Android CI was broken, etc.)

I've seen that your official website now recommends to use https://archives.boost.io/ instead of the JFrog repository.

I'm wondering where is https://archives.boost.io/ hosted. Is it going to be maintained long term or is it just a temporary measure while JFrog was down?

We're considering moving our download URL to point to https://archives.boost.io/ but we're wondering if this is now the recommended repository where to download Boost sources from:
