There is a new critical update called Remove Instance Names From URLs for Visualforce, Community Builder, Site.com Studio, and Content Files.
DANGER! DANGER! DO NOT ACTIVATE!
This changes links for visualforce pages. <domain name>.visualforce.com replaces <domain name>.<instancename>.visual.force.com.
For whatever reason, this does not work with Visualforce tabs or with buttons that link to visualforce pages.
With the critical update deactivated, the link for visualforce tab is https://<domain name>.<instancename>.visual.force.com/apex/TimeEntryCalendar?sfdc.tabName=01r500000003bNn.
When the critical update is activated, the link for the visualforce tab is https://<domain name>.visualforce.com/apex/TimeEntryCalendar?sfdc.tabName=01r500000003bNn.
The problem is that clicking the "activated" link yields this:
This site can’t be reached <domain name>.visualforce.com’s server IP address could not be found.
In my case, it was a really big problem because the visualforce tab was the default home page. So activating the Critical Update essentially locked all of my users out of salesforce.com.
This also fails with a simple button link to a visual force page.
If you assign a url to a button or type the link in - /apex/TimeEntryCalendar for instance, it works fine when the update is deactivated.
But activate the update, and it fails on just the simple link.
