Too many attempts?

Tried logging into the forums just now with my battle.net account (email) and password and couldn't for a bit and kept receiving a "Too many attempts" arrow pointing to the account name field. Just to be clear, this was attempting to sign in to the forums, not account management.

It seems to be fine now however. Temporary forum hiccup or legitimate reason to suspect someone is trying to access my account? Was able to log into account management with no hassle and all my characters and items appear to be intact.

I have an authenticator attached so I'm not particularly worried, just paranoid.
