Ah great. My Starlink hardware just arrived.
I wasn't charged any high-demand surcharge though. I probably wouldn't have ordered it if I had to pay one of those.
I don't think my area will have high demand for Starlink anyway. Even their fastest options are slow. There are options for like 5-10x the speed around the same price in my area. The only downside: There's like a 50% chance of lightning frying my modem each year, and it takes like a week to get a tech on site.
Starlink is a great backup connection. It's cheap to just keep in standby mode (~$15/month, IIRC). An unexpected, heavy surcharge might be a deal breaker though
