Performance
The last 24 hours, all hosts combined. When one host fails, BazaarLink automatically routes to the next healthy one.
Hosts
The same model runs on several hosts, and each host's price and speed can differ. BazaarLink chooses by price, speed and stability, and switches to the next host when one misbehaves; you can also pin a host in the request.
