We provide basic support on majority of our services unless stated otherwise. You can see what we provide in basic management and our advanced management options here: https://iniz.com/server-management
In short, we will try to help where we can excluding any issues related to your custom app/sites (we won't cover issues such as third party plugins you are using on your website for example). You can view our Looking Glass for primary locations where you will also find the test IP/files.
