Hosting, banda e ingegneria di rete, scritti dal team che gestisce l’AS 25198 — capacità illimitata, peering, storage e i compromessi che ci stanno dietro. Gli articoli sono pubblicati in inglese.
The machine is the easy part. Address reputation, geolocation and an abuse process that answers decide whether the service works at all — then conntrack, MSS clamping and IPv6 decide whether it scales past one node.
A game server is a simulation loop with a fixed deadline, and no amount of cores makes one thread finish sooner. What to buy for a single instance, what to buy for density, and why jitter beats port size.
The edges take the load until a purge, a deploy or a cold region sends every one of them to the origin at once. Hit-ratio arithmetic, the cache headers that are the whole contract, and which machine to actually build.
The failures in colocation are rarely technical: missing rails, a dual-PSU server on one feed, nobody with the IPMI password. Space, power, network, remote access and paperwork, in the order they cost you a day.
All three are still shipping because they solve different problems. The interface ceilings, the queue models, the DWPD and power-loss specifications that actually matter, and how to pick the mix for your working set.
The port sets the ceiling; disk, TLS and connection state decide the number you actually reach. Bitrate arithmetic for every tier, a worked 10 Gbps live example, and the three resources that run out before the network card does.
Transit buys reach to everywhere by the longest road. Peering buys a short path to the networks you actually send to. What each one costs, how BGP picks, and how to read the difference from your own shell.
Same network, same team, a site that finally explains it. Specs and prices in the open, live stock on every server table, and eight languages.
Unmetered is not unlimited-with-an-asterisk. It means you pay for the port speed and never for the bytes that cross it — here is what that changes in practice.
