We are working on adding a web page snapshot tool to view a domain's index page using the current/real time name server settings. A lot of the time when a user notifies us that their domain isn't working properly it is because their computer or ISP has the previous name server settings for their domain cached. With this tool, they would be able to view a non-cached version of their web page.
And for everyone else, here are the steps to access the snapshot tool: (http://www.dynadot.com/help/question.html?aid=136)
1. Log into your Dynadot account. 2. Click the "Domains" section link. 3. Then look for the "snapshot" link in the "Name Server" column for the domain you want to check. 4. Click on this link. This will pop up another window showing a snapshot of your domain.
Also, please feel free to post any feedback or suggestions.
