I've tried to use my Westpac Mastercard twice this morning and both time it failed - not declined.  I tried my wifes and got the same result.

Rang Westpac card services and had to wait about 10 minutes - not long but unusual - and was told that Mastercard had a power fault and would be offline for up to 2-3 hours.  Considering I tried to use my card at 8am - that's 5-6 hours offline!

I can only imagine the carnage at Pak n Save etc when people get to the checkout and cannot pay!

Anyone else having a problem this morning?
