I was an early adopter in the US. I've been relying on Xero and it's APIs for my business to operate since 2009! This is the first time I can ever remember an outage like this. There are definitely some things that annoy me about the product, but I understand that when you deal with a companies general ledger, you can't afford to "Move Fast and Break Things." I do not envy the sysadmins getting woken from their sleep right now.
