Support is good; the product works as advertised. We have a Slack connection with them. So we can basically ask for help, live, engage, and ring when they respond. Very quickly.

Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users.

We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers.

I think Fastly could improve by improving the documentation and having some code examples so that it is easier for developers, since at the beginning it becomes a bit complicated.

Stronger analytics would be helpful, like showing configurations that haven't served a certain amount of traffic in a while. With many properties, things can get lost track of - duplicates or unused configurations not properly decommissioned.

It is missing a "staging" platform to deploy a test configuration with all of the real settings, which would allow us to properly test before putting it into production.
