Try restarting the application pool in IIS that the website runs under.

My hosting service got it going again, but for next time... How do I restart the application pool in IIS?

Ok good.I'm going to guess that's what they did.
You won't be able to do it since your site is at a hosting company. To restart the application pool you have to have access to the web server either via remote desktop or at the actual computer. You can also do it via command line as well, but again have
to have access to that server.. However a quick run down through the IIS management console

My website is not in there the websites folder, is it supossed to be? Or that's because like you said, my site is at the hosting company?

Yea I'm going to guess that. Because your website is hosted on your hosting company you won't see any of that stuff. Usually hosting companies will make a special interface for you to see what is in your website and that's it. They won't give you direct
access to the server unless you pay for that type of package (if it's even offered). Like Go Daddy has dedicated servers and virtual dedicated servers which is like having your own server and you're not "sharing" your hosting with anybody.

The "Service Unavailable HTTP Error 503" errors can also come around if you are running 32-bit mode on a 64-bit Windows 2008 server. In this case, just restarting the App pools won't help, you will also need to type the following in a command prompt:
cscript c:\inetpub\adminscripts\adsutil.vbs SET /w3svc/AppPools/Enable32BitAppOnWin64 False

Well thanks wtroom and bartekm. I guess I'll just tell my hosting place every time it happens and they'll fix it for me.
They mentioned it has to do with too many errors, so I'll have to work on that too.

hmm, am I supossed to mark any of these as answer? Cuz they didn't actually help me with my prob.
But, why not?

It's so random cuz I just got it again - it only happens after I upload the site again and only sometimes. Does anyone know how I can prevent this?

That is a bit odd. Sometimes, code can cause the application pool to crash. Then again sometimes the application pool itself will crash. I've never gotten a 503 when uploading to my hosting company. I usually got the 503 when trying to community between
2 servers on the network itself inside an intranet. I wish I could offer some more advice for right now, but I can't really think what would specifically be doing it.
