Regarding the NA server issues
If you played in the past maybe 30mins to an hour ago, you probably experienced either you having DC issues, your team having issues, or the other team experiencing it. Currently it looks like it's unstable, AVOID PLAYING UNTIL FURTHER NOTICE.
Some think it's an issue involving the new champ(?)
for me it was:

no one had aurelion sol, so i doubt it was related to him.. either way play it safe, don't start ranked or anything and wait until the issue is fixed.
