If your router reset, something else was likely going on. Unless the flooding caused the router to overheat or something... in which case it may be time to take a closer look at your network as some replacements/upgrades may be needed. For it to reset, either someone forced it through an exploit or other form of remote access, or it is getting flakey and is not holding up well under heavy loads. If your hardware is managed by your ISP, something may have been going on from their end that caused a reboot. Even though it was an extremely unfortunate time for it to happen, it doesn't necessarily mean it was specifically from a DDoS attack. Hard to prove either way without any kind of log for the bogus connection attempts and such. A DDoS will basically just flood your network with sort of half-open connections so it exhausts resources and bogs the crap out of things. And it usually lasts for quite a while... it isn't something that generally recovers with a reboot--unless that results in you getting a different public IP address, as that is what they are attacking. Fill out the report form here, including the link to the match from your history. They may be able to find some wrong doing through their logs. May want to note the time/date and forward the details to your ISP as well, in case they may be able to track something through either your modem's logs or elsewhere within their network.
