Hub Transport redundancy query

Hi

Let's say I had two AD sites, Site1 and Site2.

Each site had two Hub Transport servers in it each, Site1HT1, Site1HT2, Site2HT1, and Site2HT2.

Would I be correct in saying that if Site2HT1 went down, mail to Site2 would still be sent from Site1HT1 and Site1HT2? If mail didn't go to Site2HT2, but instead queued on the HT's in Site1, where would be the best place to start troubleshooting?

If I brought in an additional site - if the only HT in this site went down, would mail queue at the closest possible HT (how is that decided? - network bandwidth or AD site cost)?

Hub transport servers are resilient by default. So, if one hub server in a site fails, the communicating hub will try the second one automatically. Site to site hub transport servers use "invisible" connectors to communicate.

Nothing to be done. It will be fault tolerant.
