 Subject: [apops] survey on BGP damping

 Hi,

 We are conducting a survey of BGP damping deployment and would greatly
 appreciate if you could take a few minutes to answer the following
 questions.  There are a number of interesting results and various
 recommendations for damping settings.  However, we have found only limited
 information on who does(does not) deploy damping and what parameter
 settings are selected in practice.

 If you are willing to participate, please send replies directly to us.
 We will collect the results (removing any private information regarding
 specific sites) and post the results to the list.  Thanks!
