Of course this happens the day I'm travelling from Sendai to Tokyo. My 10:22 shinkansen was cancelled at 3pm ish and we were told to get on another shinkansen that was scheduled for before 10am. As you can imagine, the non reserved sections are packed, with numerous people standing between compartments.
We've traveled quietly slowly for one station and have been stopped at Shiroishizao for a bit.
