No the buses did not run.
We all dealt with it by staying home for the day and doing a bit of work from home.
And as I recall, I made a lot of progress on a uni assignment too.
There was a massive flood in May, and the same sort of thing happened ... no buses for the morning, so no work that day.
I'd like to work from home much more frequently, but my office isn't really set up for that except on odd occasions.
Two "events" in 5 years that shut down the roads and buses for the morning and early afternoon isn't that big of a deal.
