Chrome breaks Split Brain DNS 0 Recommended Answers 1 Reply 12 Upvotes

At my organization we use chrome for enterprise. 

The issue we are experiencing is the fact that the way chrome caches information breaks split brain DNS. 

Our default homepage is https://intranet.domainname.org when on site the internal DNS server points the users to the proper web server. When off site however the external DNS server points users to the external site when trying to access that same url. Same URL two different IP addresses depending on if they are onsite or offsite. The TTL for these DNS records are set to 30 seconds. 

Now, if I take my laptop home and connect it will work properly and open the external site, however if I then connect to the VPN or take the machine onsite it will still connect to the external site. DNS isn't the issue, if I do a ipconfig /flushdns the issue continues to remain. the ONLY way to get it to work again is to clear the google chrome cache specifically the cached images and files. once you do that everything works again. This really seems like a bug, if not is there a way to work around this ? What is the proper configuration for accomplishing this? Where can I suggest a feature to allow admins to prevent caching on specific domains?
