Some of my clients are having problems when their local DNS providers have temporary issues and they cannot connect to their site. Everyone else in the world can get to it just fine, but one geographic area of the country seems to be cut off for periods of 15 minutes to a couple of hours. Other than setting up a fallback server somewhere else are there any options that I can set up to mitigate the problem when it occurs? I had a thought that I could route them through a proxy server somewhere else in the world to allow them to get around the local DNS outage but could that be set up automatically somehow? So that if a person gets a DNS error for a site on the server it would fall back to send them through a proxy server?
Someone else suggested that to me today too. I think we are going to try moving their DNS over to Cloudflare and see what happens.
