Bitstamp not showing on ticker

[Arcteryx]

I was watching bitstamp price on a ticker app that I have and noticed that the price just stopped all the sudden for 10 minutes. That was strange I thought, because it is constantly trading and almost have some kind of movement. Then it all the sudden cleared without any numbers just hyphen for about 3 minutes.
What happened to their exchange? Outage maybe.
It is back now but that was weird because I was watching it for 2 hours waiting to buy at the right time then this happens it is bad for a high volume trader who relies on their price if they are buying for a client or themselves.
