Is it normal to see a dramatic drop in visits during the propagation of server change?

I have upgraded my Godaddy server from VDS to a much faster DS last night. I've seen a dramatic drop in all visiting traffic that i normally get. How long will it take for the site to be completely propagated globally? because i also get a lot of traffic from China and India.

also, would it hurt my SEO traffic if i redirect all domain ext. .org .net .am .fm .etc. to .com domain ext.?Is it normal to see a dramatic drop in visits during the propagation of server change?
I assume Virtual Dedicated Server and Dedicated Servers are what you meant by VDS and DS. If the IP address of each was different and you have moved from one to the other you'll need to update your domain name server's record [DNS] this will be with whoever you purchased your domain from. Once done it can take up to 48 hours for ISP DNS caches to be updated, maybe longer so without leaving a redirect page on the old VDS at its IP forwarding traffic to the new one there's little to do but wait.



It will not affect SEO to forward multiple domains. In the case of Google only the main domain will have a page rank once the others are logged as redirecting they will be dropped from Google's records. Other search engines may vary. This is to stop a person buying a thousand domains and pointing them all to the same site.Is it normal to see a dramatic drop in visits during the propagation of server change?
It is normal to see a drop because of server changes.

Propagation take usually max. 48h.



Regarding redirection it can not hurt to redirect a couple domains but a redirecting a log domains ask for flag. I would not suggest to redirect more than 5 domains to your main domain in one time.

It is better to write unique content for each of your domains instead of redirecting.
