We have been a Coreix / dediFast customer for almost 2 years now and the service they continue to provide to us is flawless.
: Not really had to use support much but whenever we did the response was frightening (in a good way). We are not used to getting less than 5 minute replies from any company yet Coreix reply to tickets within 5 minutes. They boast 24/7/365 onsite support and we tested this out on a couple of occasions when we called the support line between weird hours of 1AM - 3AM they always answered the phone and were happy to help.
: We have had 100% uptime. We use the premium network and downloads/uploads are always fast.
As for pricing etc, they are not the cheapest but definately worth every penny. We have approximately 26 servers with them now and we intend to have many more in the future.
We have used both Coreix.net and dediFast.net and they are the same company on the same network etc. the only difference as far as we know is the server range. Please correct me if I am wrong.
Keep up the good work guys and a special shoutout to the techs for putting up with us
