Switched sites server/hosting and DNS. How can I tell when running off new server? So currently the site is sitting on both servers while I wait for the DNS to propagate to the new server address. Once it’s complete I will delete the site on the old server. How can I tell when DNS propagation is 100% complete? Is there a tool to look this up?
And different servers across the world will update at different times right? So to be safe I guess I should just wait the 48 hrs. Still though is there a tool? I googled it and tried some DNS lookup tools but none of them seems to show me what I was looking for.
When I moved to a new host, I placed a comment in the HTML at the new server so I would know for certain which place I was getting the content from.
Also, you should be able to find some free web proxy servers around the world you can use to test which server is delivering the content. This will help with DNS caching issues as they will not have your old IP address cached whereas your computer or ISP may.
Bear in mind, just because DNS has propagated for you, it’s not necessarily propagated for everyone else. Many visitors may be on ISPs and networks that have long TTL times, or even ignore them :- you can never be 100% certain that ‘everyone’ is ok, but just make a judgement as to when (as wwb_99 has pointed out) the majority are seeing the new server.
