Exception caught if error is raised in Service Error Handler

Question

Can any one help me on this? Im not able to understand the funda for the behaviour?
Proxy Service A calls proxy service B using Publish action. In proxyservice B - service error handler, Im raising an error with customised message. Proxy service B routes to another proxy service C which routes to Business service.
If my business service gives me timed out , error is handled at Proxy service C error handler , and again Proxy Service B error handler is invoked. Here my code stops where Im raising the error.
When I raise error in Service Handler where it is being caught?
Thank you in advance.

Hi Vyshnavi,
There are four levels where you may define an Error Handler and it will catch errors related to this level only. If it could not handle any error reached to it, it will propagate the error to the higher level error handler. All errors which can not be handled at lower levels, System Error Handler, handles those.
