Getting 503 error on my website on X03

[spbcx10m]

All services are shown as operating normally on the service status blog, but I'm getting this error message when I try to go to the home page.

'Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.'

I can log into cpanel OK and see and edit my sites files.

Hi,

Your website currently appears to be loading fine here. Are you still facing this issue?

Thank you,

Thank you,

It came up again shortly before midday London time, so was probably down for about 1 1/2 hours. Any idea what might have caused it?

Thanks,
Peter

Experiencing the same issue currently. I assume it's a server-side.

Same issue with my blog (wordpress install) on http://shifat.ca/blog
My "main website" which is just made with HTML on http://shifat.ca/ works fine however.
I'm on xo1.

UPDATE:
Tried loading my blog through my cellular data connection (mobile phone) and it loaded up fine. I try to load it through my computer, I get the error. I'm assuming this is happening because my internet connection is slow right now since my ISP is running maintenance work this week.
