I had just set out for AMS at the time this thread was posted!

In the end, I only just made my flight (which was over to London for an Olympic final, so I'd have been very annoyed to have missed it). But it wasn't the IT problem - I saw no evidence of delays, and my flight left on time (more or less, I was one of the very last to board).

The problem for me was that there was a problem on the train tracks between Hoofdorp and the tunnel so most services to Schiphol from the south were cancelled.
