Hello!
Our Assets Provider is currently having issues: Wasabi Technologies Status - Investigating issues in us-east-1 region
Our servers on the other hand should not be slow. If you’re experiencing lag/slowness that should be the world Size or might be Browser based, as well as Module leakage and so much else.
You can go through these helping posts to keep your world healthy:
World Size Check and Trouble with Modules, How to fix/turn on your browser's hardware acceleration
These usually fix the world up, and we recommend to keep your worlds as small as possible.
If you’re still experiencing lag/slowness of some kind after that, or you don’t think that is the reason, we would love to have a look at the issue.
