Why have there been so many power outages this week?

Please tell me if it's just me, but it seems like there have been a bunch of scattered power outages this week. For example:

• the big one in Ohio City/Tremont yesterday
• little ones here in Lyndhurst yesterday when a couple utility poles spectacularly blew up yesterday
• my colleague in Cleveland Heights lost power last night
• another colleague in Westlake lost power on Tuesday
• yet another colleague around Old Brooklyn lost power today
• a family member in Shaker lost power today

Is this normal and just happens to be all people I know? Is it an effect of the thaw after the really cold temperatures? Solar flares? Obviously it's all because we have aging infrastructure etc. But what's going on?
