I say keep playing, suspensions are one thing but a ban is different. I get incredibly upset if I'm playing a normal game (still under 30) and someone disconnects, even if it's for a couple minutes it puts our team at a severe disadvantage. I understand that mistakes happen but it's hard to battle back from being so far behind. It doesn't mean you deserve to be suspended it just means that I'm probably more likely to report you for going afk.
Once you get sent to the tribunal things get a little silly since I hear people auto-punish a lot for the bonus IP (even though it dilutes their voting power) and when looking through the tribunal they won't see that you had an emergency or your game crashed they'll just see you're bad score (I assume) and the fact that you were under-leveled at the end (unless it went on for a long time).
However Riot deals with all the perma bans, which makes it much easier to appeal (and much harder to be banned in the first place) it really sucks you were suspended but have faith that Riot won't screw you over royally (no promises)
maybe try and get a more stable connection before starting?
