 - Tier 2 when the load zone has 1000-4001 VUs
 - Tier 3 when the load zone has 4001-5000 VUs
 
+Tier 1 instances can host up to 300 VUs
+Tier 2 instances can host up to 1200 VUs
+Tier 3 instances can host up to 5000 VUs

 Regardless of the tier, the amount of resources (CPU, Memory, Network) per VU is the same.
 For example, if you start a test with 400VUs, k6 uses 1 Tier 1 server,
 meaning that the traffic generated from our service comes from 1 IP.
 
 If you start a test with 1000VUs in a single load zone, k6 uses 1x Tier 2 server.
-If the same test is started in 2 load zones, k6 would allocate 500VUs per load zone and use 2x Tier 1 servers.
+If the same test is started in 2 load zones, k6 would allocate 500 VUs per load zone and use 4x Tier 1 servers.
