Here’s a thread from one weekend when i did have a serious problem. Turned out there were problems all over the web but towards the end it may have helped them find an issue with some internal amazon routing:
I’m posting it because there are some additional resources there including them talking about cloudfront, the CDN service that provides some of the data aside from the individual planet servers and login servers, if you want to poke around.
Scrolled back through this thread I don’t see that anyone specifically mentioned the chunk download rate or whatever it’s called in boundless. If you have a stable but slowish connection you can adjust that to affect how much the game is trying to pre-load.
I’ve occasionally had some problems like others here mention, around specific times of day and whatnot, but have enough going on here I was usually able to see that several services “suddenly” had problems in these consistent patterns and eventually, the ISP replaced the main cable for our whole neighborhood.
