Ask HN: Is AirBnB getting too popular to cope?

I'm looking to stay in New York this week, so I went to the AirBnb iOS app, attempted to log in, and received the message "Version (null) of the AirBnb app is now available", so I attempt to update but according to iTunes UK store I have the latest version. So i delete and reinstalled the app.. Still no joy. Looking at the uk app store reviews reveals tons of users with the same issue.

Next step, went to visit airbnb.com on mobile safari... No joy, redirects to the uk site then to a blank page.

So I reluctantly visit the web site on my laptop, finally works and I find a place, enter my credit card details and relax knowingly reservation has been secured. Nope. 15 hours later the booking is rejected as the room is unavailable. The next booing was also rejected. Three more requests have yet to be responded to.

Time to book a hotel? Or is this an Airbnb UK issue?
