I had a look at your website, and it’s down for me too. I see a page saying “The connection has timed out”.
It seems that the IP address your website is hosted on, 185.27.134.223, is currently down, and has been since 7:00 UTC this morning.
Usually, such issues are caused by disabling the IP to stop a DDoS attack, but it may also be a side effect of the PHP version rollback to fix the GD extension issue that many have been suffering from.
In any case, it’s not a problem caused by you or your website, and there isn’t a lot you can do about this except for waiting for the IP address to come back up.
Unfortunately, because I don’t know the exact reason, I cannot give you any estimate as to when the issue will be resolved.
We’re sorry for the inconvenience caused.
