When in doubt, clear Chrome.

We were in the process of migrating a few domains onto our hosting servers. After changing the DNS on the sites, we noticed the propagation went through quickly and smoothly. A few tricks to keep in your back pocket if you notice sites working on the new server one browser and not the other is to go into your local services (Windows), and turn off the DNS Client service to stop DNS caching. In Chrome, the browser likes to cache (a lot), so you will want to go into advanced settings and go to “clear browsing data” and check “cached images and files”. I recommend doing so after completely shutting down and restarting Chrome. In addition, Chrome has a lovely habit of not completely shutting down so you might want to check your processes to see if Chrome is open.
