Our hosting provider Rackspace encountered some unexpected network issues during a scheduled maintenance window. This in turn has caused some intermittent downtime of the marketplaces. I can see that a few people have encountered problems trying to deposit money, or make a buy now purchase. It appears as thought the worst of the connectivity problems is now over, so if you encountered a problem please try again.
I am waiting on confirmation that the issue has been resolved from our hosting provider and will update this thread as soon as they do.
