[Development] Continuous Integration issues - Coin temporarily down

[Jedrzej Nowacki]

Hi,

  Yet another update. We narrowed down the IO issue. The network update from 1G to 10G, mentioned before, brought compellent into the picture and that one didn't want to cooperate nicely with our btrfs installation, for an unknown reason.  The link will be downgraded and we would go back to a SSD storage as soon as possible (currently there are some disk operations that can not be interrupted). 

  Regarding 5.10 branch, it is still locked, but I guess it is not a surprise. https://codereview.qt-project.org/#/c/209970/ needs to be get integrated, but in the current hostile conditions it is not easy.

Cheers,
   Jędrek

And now we are experiencing unexpected, extremely slow IO on the OpenNebula
host. Our IT is working on it, but I'm afraid that nothing will pass until it
is fixed, we run at ~5% of standard computation power.
