[llvm-dev] LLVM APT Repo

Dear All

Recently we noticed that outgoing traffic from APT repo increased
significantly. It turned out that the 90% of these requests were
originated from cloud hosting services (e.g. Amazon AWS / EC2, Google
Cloud, etc) with the bandwidth of more than 25 Gb daily.

We suspect that the majority of this traffic was generated from poorly
configured CI systems that fails to cache the packages they
downloaded. We strongly suggest everyone maintaining such a system to
review the configuration and enable the caching / review the package
fetching policies. Otherwise we will be forced to throttle the traffic
to from APT repo to AWS / Google Cloud to allow better serving
ordinary LLVM users.

Thanks for understanding
