having problems with my club’s subdomain alias after initial setup

Yes, I wasn’t referring to the primary domain that we are on here, or the peer2peer.toastmastersclubs.org subdomain, but rather the domains at:
toastmastersclubsDOTcom
toastmasterclubsDOTorg
toastmastersclubDOTorg

and their various behaviors for their subdomains that are going to make it difficult for debugging whether there is downtime or just a typo somewhere. I was trying to avoid linking to them to give them any benefit from what they are doing.

I will bring these findings back to my club and let them decide on a course of action.

Those domains are not ours, how they are treated on the web is not under our control.

You need to take more care when typing.
