Coral CDN (content distribution network) may be a solution if you can't reach a website because it is either blocked by an administrator, slow or even completely unreachable because of technical issues. Filters and restrictions become more common on the Internet for instance. Schools and workplaces block access to unwanted sites many times using large blocklists and applications that update the list of blocked sites automatically.
It is clear that companies do not want their employees to waste work time browsing sites and services unrelated to work. It is not only a matter of getting less done because time is spend on other activities, but also about bandwidth and other resources that are used in the process.
Still, companies may prevent employees from wasting time finding ways around the protection that is in place.
Corel CDN caches websites, thus making them available even though the original website may be off line or blocked. To access a website you simply append .nyud.net:8080 to the url. For ebay.com it would therefore be: http://www.ebay.com.nyud.net:8080. Please note that this works only if the web address has not been blocked by the firewall. If only the site IP has been blocked, you can usually access it, but if the administrator has blocked access to ebay.com, you won't be able to use this trick to bypass the block.
You unfortunately have to append this manually to every url you want to reach. That is, unless you are using the Firefox web browser. Coral CDN offers a firefox extension which allows you to either Coralize this page or Coralize this link which means that you do not have to append .nyud.net:8080 manually to the url.
Finally they also offer a bookmarklet which should work with Internet Explorer, Opera, Firefox and Safari as well. Drag the bookmarklet to your bookmarks toolbar and use it from there.
Please note that I can't guarantee that you will be able to view the cached page and that this probably does not work with dynamic or personalized pages. (Email, Ebay account)
Update: It is no longer necessary to append the port to the address, which means that you only need to append .nyud.net to the original address to open a cached copy of it. You can also use the form on the official website to paste a website into it that you want to access a cached version of.
