bf2142.uphero.com with sleeping and error 404.
what do you mean about the 404 error?
Please take a look at this topic
now he slept!
Your site slept from 15:00 - 16:00 GMT
If you saw the 404 it may be just as it went to sleep but nothing to worry about.,
If you still see sleeping page - you may need just to clear browser history/cache.
ok , very good !!!
