Glip update at 10am?

glip was working well for me this morning 3/12 until about 10am est. when it told me to click update when prompted. I had to close my browser when i did I signed back in but no calendar or ability to do much of anything within the app. Why would the service be getting an update in the middle of the morning during a work week? It's hard to use an all in one app for my calls and schedule if I cant see my schedule or add to it.
