Connection issues with Azure DB from SSMS
Let start by making sure you are using the current IP of your Azure SQL Database server. Let's ping the name of the Azure SQL server. The ping will fail but it should also return the current IP of the SQL Azure Server if DNS resolution is working.

C:\&gt;ping &lt;myserver&gt;.database.windows.net

Pinging data.sn1-1.database.windows.net [65.55.74.144] with 32 bytes of data:
Request timed out.
Request timed out.

Ping statistics for 65.55.74.144:
Packets: Sent = 4, Received = 0, Lost = 4 (100% loss)


Now try to telnet to port 1433 using the IP address returned.

C:\&gt;telnet 65.55.74.144 1433

If Telnet is successful, the window will change to a completely blank screen. Try connecting with that IP using SSMS again. If telenet is not successful, try tracert to identify at what step it fails to reach the Azure SQL Database server.

C:\&gt;tracert 65.55.74.144
