     36  1. Physical layout: where are the servers? Where are the data centers? Nearly all servers are hosted in either Telehouse or XO (about 5 - 8 physical servers in each location), both in Manhattan. [wiki:support-contact-providers See contact information for main providers]
     37  1. Virtualization: almost all servers are KVM guests.
     38  1. We have three types of guests
     39   1. MOSH: This is an acronym that doesn't spell anything. It refers to guests that provide web and email hosting for most May First/People Members. These guests are connected to our control panel so members can easily add/modify/remove services.
     40   1. Dedicated MOSHes. These are just like regular MOSHes except they are dedicated to a single member. The dedication allows them to run mod_php instead of running php via fcgid and suexec, which is necessary on a shared machine for security reasons. mod_php runs much faster
     41   1. Single purpose: we have a number of guests that just provide one or a few dedicated services, such as our freeswitch server, DNS servers, etc.
     42  1. [wiki:puppet Puppet]: our system for managing servers and services
     43 1. Debugging common problems
     44  1. [wiki:debug-email-delivery email and email list problems]
     45  1. Debugging compromised web sites
