+# Infrastructure
+
+## Why (ideal world)
+Areas where we could improve
+* serve the whole world web
+* redundancy
+* low maintenance (labour), but maintained, supported and observed
+* understood, documented and transparent
+* sustainable (financially and environmental)
+
+Other (okeish) things
+* secure and trusted
+* privacy considerations
+* scaleable
+* no cost to use
+* ethical
+* hosted or project owned hardware?
+* minimal but futureproof
+* provides (substitutes etc.)
+* efficient operations (bandwith)
+
+## What is our infrastructure
+* Build farms
+* Security and trust
+* Services
+  * QA
+  * issues/bug tracker
+  * git
+  * website
+  * package search
+  * mailing lists
+  * DNS
+  * IRC
+* substitutes
+* sysadmin
+  * updates
+  * software e.g. guix deploy
+  * support
+  * incident response
+* money, donations
+* location, hosting
+* virtual/physical hardware
+* state, storage
+
+## Ideas for improvement
+* mirroring
+  * use a CDN
+  * peer-to-peer hosting
+* equivalence ignoring reference hashes
+* substitutes
+  * storage for the Bordeaux build farm
+  * how long do we store them (scientific community "loves" substitutes for 
the past)
+  * prepare for the loss of MDC hosting (Berlin build farm)
+* pay/financially support people providing hardware
