Breaker trip (rack power cascade)
Each rack has a power budget, and the breaker that feeds it doesn't care how important your servers are. Pack too many machines into one rack and the moment their combined draw…
-
Component failure (PSU/Disk/Fan)
Real hardware has pieces that wear out. PSUs hum and quietly die. Disks start throwing read errors. Fans seize up. The good news: you don't lose the host. You lose ONE part.…
-
Host categories (shape vectors)
Not all servers are the same shape. Balanced is the general-purpose workhorse that handles a bit of everything. Memory-optimised carries more RAM per core for databases and…
-
Each customer tier comes with a p99 latency target — the slowest 1% of their requests must still come back within X milliseconds. It's deliberately about the tail, not the…
-
MTU is how big a single chunk of data is allowed to be — "jumbo frames" are simply larger chunks, so the network spends less time on packaging and more on payload. A VLAN is a…
-
Servers and switches all draw power, and that power comes through a rack circuit with a hard ceiling. The garage rack runs on a 3kW budget; a standard rack is 8kW. Add up the…
-
TCP latency / RTT (p99 budgets)
Latency is the round-trip time for a request: the customer asks, your servers answer, the answer travels back. Every customer on a Silver, Gold, or Platinum plan buys a promise…

Thermal runaway (cooling cascade)
Every server you run throws off heat, and your cooling has a ceiling just like your power does. If the heat your fleet produces outruns the cooling you've installed, the room…
