Comcast and the Case of the Mysterious Repair

Somehow Comcast seems to have fixed my cable internet service once again without entering my home. The only correlation I can find is that whenever we have a really hard rain or a lightning storm (both fairly common in South Florida in the Summer) my internet connection goes to hell. Within several days of the outage, the service is back up and faster than ever. Here are my speed test results from DSLReports.com for this morning, which I ran while I was on the phone with Comcast customer service cancelling the appointment that I obviously no longer need.
