All services including the Zoho website are currently (starting 8:25AM PST) inaccessible due to a network issue. We are currently looking into it. Will keep you posted. Please follow us on our Twitter account for updates.
Update (8:46AM): It looks like we have a power failure in Equinix co-location provider. It effects multiple customers in that data center.
Update (9:15AM): The power is back up in the data center. We are working to restore the services. Will keep you updated.
Update (9:32AM): The power is up. We are making sure there is no data corruption before we bring the services back up.

Update (11:55AM): The reason it is taking time is because the database clusters lost sync internally. It is taking time to sync them back. Once done, the services will be restored.
Update (12:10PM): Zoho Support is Up. Due to Mail dependency, the mail part will work after Zoho Mail is restored.
