We will be offering two types of SSL service, Server Name Indication (SNI) and Virtual IP (VIP). SNI will be significantly less expensive than VIP when this service is launched, however unlike VIP it does not work in all browsers that support SSL. VIP is a premium service with a dedicated IP and full browser support. Both VIP and SNI support wildcard certificates and certificates with alternate names.
We look forward to making this widely available as soon as possible and as always we welcome your feedback in the group.
