Fast Search & Transfer was ones one of the biggest players in the enterprise search filed. But things have changes after they were acquired by Microsoft. Now it looks like Microsoft is pulling the plug on FAST Esp, there main product. Normal support will end at 7/16/2013.

More info about end dates are available at Microsoft Product Lifecycle Search page.

Microsoft will of course continue to provide the Fast Search for SharePoint search engine, but it is sad that they do not want to provide an enterprise search product that is not tied to SharePoint. Customers will have to look to other vendors.
