[AG-TECH] New StaticBridge Service Announcement

[Andrew Rowley]

Hi,

Thanks for the feedback.  This was due to an error that only became apparent
when the load was high on the bridge.  It was doing a pointless loop that
got bigger as more people joined, and so resulted in the socket timeing out
before the results were returned.

This has now been fixed, so thanks to everyone that was trying this for a
quick bug fix!

Let me know of any other problems...

Andrew :)

Hi;

I tried your new bridge service yesterday and today and I am getting errors
from 
the web site when I request that a bridge be started. There is a very long
pause 
before the web site returns a response (if at all), and the response is
usually 
an error message:

Unknown Error

An unknown error has been detected. Please go back and try again

If you do not think that you should be getting this error, please contact
us.

Click here to return to the bridge setup page.

This seems to occur for both manual and preset bridges.
