Slingshot: Hey guys,
So there is traffic prioritisation on the unlimited plan (even the old Plus plan) which can cause some slowing down for unattended browsing during busy times. Note this isn't throttling where the max speed of any particular type of traffic would be limited, instead it's a tweaking of, well, the priority of the type of traffic to make sure that people who are doing things that need an immediate response still get the best possible performance. Hope this helps!
What is "unattended browsing"?
