Re: 200mb/s for "10minutes or so" = ~15GB
The AUP has this clause:
"EXCESSIVE USE OF NETWORK RESOURCES. SpaceX reserves the right to engage in reasonable network management to protect the overall network, including analyzing traffic patterns to optimize services and preventing the distribution of viruses or other malicious code. SpaceX reserves the right to immediately restrict, suspend, or terminate Services without notice in order to protect the network or minimize congestion caused by unauthorized use."
"Traffic Neutrality. We treat internet traffic equally, without discrimination based on content, sender, application or service. Network management practices are deployed based on technical requirements for specific categories of traffic. These practices are applied in an “application-agnostic” manner, meaning that the treatment of traffic is independent of the content data."
"Distributing Data Based on Service Plan. We seek to distribute data among our users in a fair and equitable manner by (1) implementing network management policies when the demand for network resources actually exceeds supply," [item 2 is the priority service]
"Starlink seeks to distribute Standard data among our users in a fair and equitable manner. If bandwidth patterns consistently exceed what is allocated to a typical residential user, Starlink may take network management measures, such as temporarily reducing a customer’s speeds, to prevent or mitigate congestion of the Services. Bandwidth intensive applications, such as streaming videos, gaming, or downloading large files are most likely to be impacted by such actions."
"Actual speeds may be lower than expected speeds during times of high usage. Performance varies based on location, time of day and the precedence Starlink gives your data in the network based on your Service Plan."
"Starlink users typically experience download speeds between 25 and 220 Mbps, with a majority of users experiencing speeds over 100 Mbps"
So nothing explicitly says that there is a 15GB cap on single downloads... it's a rather substantial amount of data to be pushing.
Maybe at 2 am is when all the businesses etc who pay for priority kick off their backups?
