There haven't *really* been any speed limits
There are a few things we've done over the years to try and make the internet usable when there are too many users sharing too little bandwidth
- The original steam protocol didn't allow caching, as a result we rate limited port 27030 to prevent accidental steam downloads from sucking all the bandwidth. We've ceased this since implementing lan cache around 2 years ago.
- We restrict online gaming, as UDP (used for game traffic) has no congestion control, and will keep sending a decent chunk of data irrespective of the state of the connection. We'll review this after this lan
- Finally, the "fair usage team" will swing into action when people start to complain the internet is sucky. We'll look at data usage and identify those downloading, then inform them that they are doing so (Generally this is unintentional, for example origin..)
