Missed communications with our registrar caused the domain to erroneously enter 'expired' status for a brief period. The problem should be fixed now, but due to the nature of the domain name system it will take a number of hours to everyone to again see the domain.
FYI, for the future, you will also usually be able to access Bitzi via the domain 'bitzi.org', which is at a different registrar and renewed on a different period.
More details for the interested:
Our domain was on auto-renew, *and* a few days before the expiration I made sure to renew manually, seeing a confirmation page from our registrar.
However, the day *after* the expiration date, several days after manual renewal (and while I was traveling) an email was sent indicating there had been a payment problem, and the 'bitzi.com' domain was soon after reverted to the registrar's parking page. After receiving a phone call about the expiration, I was able to correct the payment problem with the registrar immediately.
