Hi, it depends on what part/site roles of the site scrashes. if the primary site crashes, you are ok because you DP and MPs are up and running. clients would still be able to get policies and validate clients statement of health. The issue will come in where if you MP is don't and clients could not validate policies and the SoH. If the all DPs are down then clients would not be able to get content when required. So in short in sure you have enough MPs and DPs standing. I would seperate the roles of MP, DP and SHV off the site server.
