I have a domain set up on my hosting account, which is a shared host.
It has been doing fine, but as the site becomes more popular the response times are getting slower and slower, and sometimes gives 503 error (it's an API, so people are hitting it and need a speedy response time).
It's got to the point now where the shared host is buckling. So I have purchased a VPS which should be able to handle the load.
My question is, instead of directing all traffic to this VPS, is there a way of distributing it between the two?
If I can have 2 A records, how does the browser determine which one it visits first?
