[OpenID] OpenId downtime

[Tan, William]

In addition to what Nat said, XRI Resolution Section 9.1.4 also
specifies that the client SHOULD attempt multiple A records returned for
a given host. So, there are at least two ways of publishing your XRDS to
minimize downtime.

Thus, if one of your OpenID server goes down, it can certainly go to the next one to get the authentication. Thus, unless all the OpenID authentication services specified in the XRDS goes down, you still are going to be authenticated.
