We have already contacted the server provider, and they are already investigating it.
It may take a few hours to solve it.
Check the status page, and the incident page for more information:
NOTE: You can still work on your apps. Our suggestion is that you use the Companion by now to preview the apps. When Compilers come back, you will be able to export it, but do not worry if it does not work as of now.
You can now build apps again.
The issue is still being monitored, as we used a different provider now. We will switch it back after we confirm its full resolution.
