With BPOS and the first version of Office 365, Microsoft has provided a web tool (Speed Test) to assist customer to determine if their internet connection can support Microsoft Online services, from messaging to collaboration [covering Exchange Onlnine but more important Lync as it may consume important bandwidth]. This tool was available from www.microsoftspeedtest.com

Since few months, this site is no longer available and many Office 365 customer (existing or potential) as well as consultant implementing Office 365 have no tool to evaluate the impact of Microsoft Online services on their internet connection.

Fortunately, there is another tool available – initially covering only Lync (Lync Online Transport Reliability IP Probe -  TRIPP), can provide a good replacement.
