Thanks for the image (and I had already seen toxic's screen cap) but I don't get it.  We are/were on the same page - bitcoinwisdom.io/markets/bitstamp/btcusd but it was showing me a high of US$56,686 and then, thinking it was old age/glasses/dreams,  I went directly to the bitstamp.net/markets/btc/usd/ website to check and neither was it showing that we had hit $57k.
 Not wanting to admit to my own frailties, I'm going to assume there was some sort of temporal anomaly, restricted to my geographical location, causing me to perceive events differently.  Also, no more fishy crackers before bedtime for me.
