Services to see if your site is working properly

[EnduranceNinja]

I am not sure how to word this but is there any free service that does a check of your website to see if it is working properly? I do chages to my website and it works well on my side but sometimes it is not the same to the people visiting my website. Examples are images work for me but not for others or links to my pages work when I try them out but my friends tell me they can't get my pages. I just wished there was a service to see if all is working well so I don't find out from others.

Thanks for your time

I find vmware a great way to check on web material I create. Mainly because you can try your web site on a different OS or browser versions. Another way would be to use a live CD (e.g. Ubuntu with Firefox) and boot that to check your site I.

I know this is not a complete answer but it could assist in checking your own work in different environments.

Search for an HTML Validator.

Also find out what browsers are having problems.
Sometimes you have to code differently to service all browsers.
Mostly IE 6 and 7, Firefox, and Safari.

You can install multiple versions of IE...
Install multiple versions of IE on your PC | TredoSoft
Internet Explorer 7 running side by side with IE6. (standalone) | TredoSoft

After that, you could also get Firefox and Opera and you'll have most browsers installed(except for Mac browsers). You could also install Links and Lynx if you want to support those.

There are services which show you how your website looks on different browsers/OSes but some cost money and they're slow. I can't remember an URL though.

EDIT: Also, an HTML validator usually won't do anything to help your site render better in different browsers since IE6 for example pretty much ignores most of the standards. And weather a website works or not for someone depends on pretty much just their browser(although there are different version for different OSes; I hear IE for Mac is a little different that regular IE).

From a visual side you can use a site like Test your web design in different browsers - Browsershots

I use BasicState and Mon.Itor.Us for uptime monitoring.

I use Selenium for interface testing. Selenium has a Firefox plugin that lets you record paths through your website and then play them back. I *highly* recommend it.
