Why is roundcube mail not opening this morning?

Roundcube mail server is not opening ( ), is anyone facing the same issue?

It’s saying this on the browser when I go here :

“This site can’t be reached took too long to respond.
Search Google for roundcubemail

Since yesterday (I think), there is an issue with the webmail server. Initially, RoundCube would start but would not be able to connect to the database. Now it doesn’t work at all.

All I know is that iFastNet is aware of the problem and working on it.
