The default timeout for network tests in Hobbit is 10 seconds. You can
change it via the --timeout=N option (N is in seconds) for bbtest-net 
in hobbitlaunch.cfg.  See the bbtest-net(1) man-page...

BB uses a fixed 20 second timeout.

Millisecs shouldn't make any difference. It's a global setting - not in
the bb-services file per service - because all of the network tests
really run in parallel. Having individual timeouts is just
un-manageable.

How many tests do you run ? (See the status in the "bbnet" column for
your Hobbit server). It's a well-known problem that Hobbit can actually
flood some networks/firewalls with connection setups, resulting in 
some tests showing up as failed one moment, and OK a few seconds after.
You might want to lower the number of concurrent tests that bbtest-net
runs via the --concurrency=N option - the default is 256.

Read The Fine Manual :-) You'll find them on your Hobbit server webpages, 
in the "Help"->"Hobbit man-pages" section.
