Ping on revivaledit

When a node is marked dead it will only be put in the dog house for a certain amount of time. Once it comes out of the dog house, or revived, a ping is scheduled before an actual API call, to ensure that it’s up and running. If it’s still down, it’s put back in the dog house a little longer.

Take a look at the Request timeouts for an explanation on what each timeout is.
