Can't Delete Subdomains

[GoombaLuke]

I have a subdomain I want to replace, but since I already have two, I need to delete one. Whenever I try to delete it, it loads for around a minute, then gives me the error message. Are the servers down or something?

What is the error message?

I know it's not my computer (tried it on two)
