Recently our area experienced a significant weather event.  Our city was without power for as much as a week and as many as 250,000 folks.

We host our own DNS servers and they along with mail and VoIP communications were down for 7 days.  We purchase our internet service from provider A, our domain from provider B, our web hosting from provider C.

When the lights went out users could no longer resolve our website (I assume because our DNS servers were down).

My question is:  Within this scenario what is the best/easiest way to insure our website is still being resolved to the rest of the world?

    you would need to have your DNS hosted as a "backup" DNS with a provider somewhere that is off-premises.
    I think there are some companies that do this type of thing, and I am 99% certain that your web hosting company would probably be able to do it. If not then certainly your ISP.

    If you cannot have DNS servers in multiple physical locations, then consider secondary DNS from a provider that is under a different ASN at another location. offers free secondary dns service.
