We had a really awful experience with our hosting provider recently...We have been with Hostforweb for over 14 years and things were good (most of the time). They migrated everybody to servers in New York recently and there was an outage because of that for almost 24 hours. Then they sent an Email telling everybody to switch the DNS (which I never read) and as a result - another outage this time more than 5 days! There were many many many people affected by this. All technical support was down during these incidents.
Now, I am looking to possibly setup a 2nd host and use them as a backup if our primary hosting goes down for whatever reason....is this called a mirror or proxy and how would I do that? I assume it would be nearly impossible to have real time synchronization between the 2 hosting accounts but I don't mind doing this manually every so often.
I will be grateful for any suggestions...
What would be the cost involved? How would I manage the DNS? Would I setup ns3.example.com and ns4.example.com and would that transfer the traffic to the 2nd host in case the site at the first host would not be loading? (How would it know the primary site is not accessible?) Are there any specific companies that offer this kind of a solution?
