+### Careful with "Up To GBit/s Instances" 
+
+AWS heavily discounts instances with "up to GBit/s" network bandwidth. These instances use a credit-based system to
+calculate the currently available network bandwidth. These instances initially offer a good throughput until the credits
+are used up which happens very quickly.
+
+In addition to the limitation on the maximum available bandwidth, AWS heavily limits the number of packets per second.
+
+!!! recommendation
+    Simplyblock strongly recommends using EC2 instances with dedicated bandwidth. Generally recommended Amazon EC2
+    instances are _i3en.6xlarge_ and _i4i.8xlarge_.
