TSQL Check Database Instance Online
How about just validating that the database you are interested in connecting to is online?
select
name
from sys.databases
where name = 'DatabaseName'
and state = 0 --Database is online
For the full reference of available columns for the sys.databases catalog view see Books Online: sys.databases
EDIT: Fix SQL query

What is the best way to check if an instance of Microsoft SQL Server is up? I have a view that spans two instances of Microsoft SQL Server but before querying it in a stored procedure I would like to verify that the second instance of the server is up with a fallback option of just querying local data.
The second instance is a linked server.
Currently I'm considering a SQL CLR function that can attempt to open a connection with a shorter timeout but I'm wondering if it's something that can be done directly in Transact SQL.
