I noticed at http://101domain.com that there's a three (3) day delay in registering new .at TLD domains. Any idea why this is? Is it just back-end processing/approval? Has anyone had it go sooner?
There's nothing I can find in the nic.at terms/legal docs that mentions a wait period. It's possible that they're just slow, and the 101domain mention is intended as informative, not a "requirement."
Why don't you just ask them? They have chat support available.
