We have our domain name registered through Spark, who appear to outsource this to MelbourneIT.

Anyway, our domain no longer resolves. Spark help desk don't seem to have a clue, and MelbourneIT say "phone Spark".

Is there anyone from Spark on here who can help shed some light on this?

I'm hoping it will be resolved by morning, but if not this will cause major issues for my work.

EDIT: I am also unable to log onto the DNS control panel.
