As a Free Hosting provider I can not say anything bad words about my own hosting site however there are lots of restriction on free hosting accounts for every free users. And we can not expect more than that at this cost, from last week we are keep getting support tickets that user’s are getting this error while they try to pull up their website..
Service Temporarily Unavailable
The server closed the connection without sending any data.
The server is temporarily unable to service your request due to maintenance downtime or capacity problems.
Due to heavy load on the server, connections may be temporarily blocked from locations that fetch an unusually high number of pages.
We apologize for the inconvenience.
If you are getting same error on your website hosted on free account that means, server where your website is hosted is down for any reason or got over loaded it may take 1-2 days to become live again..
How do you find is server is down??
You need to login in to your cpanel and the error message will appear on top.
