Might be a bit late to the game...other sites are playing it down, if your sky is clear tonight it might be worth keeping an eye out.

Last couple nights local 10pm news telling about the Northern Lights being visible and very bright as this type of thing goes...
Also the internet has been kind of off and on wonky the last couple days..
Related issues ?? Or just the end of the month ??

Space weather can affect the satellite internet, as can severe storms and so on. Auroras are very electrically noisy, with gain bandwidth products that extend to Ghz in width, so contain a lot of energy. Even though the amount of energy in the microwave bands that satellites use is quite small, the sensitivity of the dish's LNB to the interference causes the issue.
The auroras also prevent u communicating with space craft, such as the Voyager probes, and demand careful timing of launches to avoid the worst effects.
The ionization of the atmosphere from the auroras also helps in short wave reception as it increases the density of the ionosphere and the MUF (maximum usable frequency). Drag on spacecraft increases, potentially shortening their lifespans and causing re entry sooner than expected, so its not a win win situation.
Voltages can be induced into terrestrial communication cables as well as power lines, resulting in blackouts.

You have a very good point there. Starlink and it's competitors would be permanently destroyed if hit by a coronal mass ejection (the cause of the largest auroroa). Even fibre optic connections still go to and from stations full of wires and computers which are very sensitive to these things. The closer you are to each of earth's magnetic poles, the more at risk you are. Though for the largest solar events, even at the equator electronics aren't really safe.
