I accidentally got it live :) Well, I was expecting that because I have seen similar message previously in the logs.

It is called parallel nightly build of the Glasgow Haskell Compiler :D According to its official documentation, compilation and testing is very intensive, indeed.

We will see soon... Thanks for the quick help! :g
