@jaspernl hi there,
We do use vultr for hosting. However, speeds are 10GBPS and you can test the connection speed yourself within the control panel.
Resources are dedicated to each user and not oversold. This hosting is apart of our main brand, Milkk Media Group. We can insure no lag will be found. If you have any loading issues, please let us know, and we will get to work on deploying your own custom server in your location region.
