The service should now be broadly available: please let us know if you continue to have difficulties.

Take care, and thank you.

ipedro,
hi there. Our apologies about this: the service is hosted on a small cluster of servers in the Linode Atlanta region which is currently in day 4 of a DDoS attack that has resulted in service outages. We are in communications with them right now and hoping service will be reliably restored within the next 24 hours. Barring that we will migrate to an alternative provider to ensure we restore service.
Take care, and thank you.
