Bingo!For home internet. It's probably not much more load than the average weekend with poor weather. Since most people are home and there is a lot of streaming and gaming on those days. For someone with a crap ISP which can't handle that load. Then work may suffer. Really depending on if someone is just connecting to servers for web apps and files or has to video conference and remote desktop.
Some offices may not be able to handle it. If they don't have a very good connection and are suddenly shifting to employees using remote desktop.
It all depends on location. My area is serviced by fiber optics. Along with good cable competition. So, the ISP's already have plenty of infrastructure to handle the load. Areas with just DSL or DSL and one Cable provider will likely have more noticeable slowdowns. As there is little incentive to improve infrastructure.
