I think that might just be your internet my dude, and if it is crashing its probably just the sheer amount of people that play on there daily, like the adopt me game for instance, its almost always the cause of servers crashing, theres no way a single can device can handle that much traffic, so they have multiple handling it, but even with tens of hundreds of servers racked its still not enough, sometimes it isnt the servers, but the ones using them. To understand how powerful these servers are you have to realize that these things have terabytes of RAM, and the best CPUs out there, and with tons of those, it cant handle all of the traffic. Tens of millions of children sit around and play Roblox all day, almost all day. Its alot to manage.
