Hi Thomas,
Thanks for reaching out and for using BoldGrid’s Speed Coach website performance test.
I’m sorry to hear your having problems with Speed Coach. One common issue I always see is, if you’re entering your website address exactly like you did in this question, i.e. www.development.example.com
, the reason the test is failing is because there is no DNS for the www.
sub-sub-domain.
Instead, enter your website address like so: development.example.com
.
I hope this helps. Please let us know if you have any other questions for us.
