Bloomberg LP experienced a "significant" unexplained outage of its Bloomberg Terminals on Friday.

The outage happened early this morning, so it mostly impacted folks in Europe.

A Bloomberg Terminal is a really high-speed computer created for financial professionals so they can message other users and obtain real-time market data, news, and stock quotes among many other functions.

They're pretty much ubiquitous on Wall Street, and a subscription for one costs about $20,000 per year. Wall Street banks and hedge funds pay Bloomberg LP millions of dollars a year to buy terminal accounts for their employees.

So what did Bloomberg terminal users do when their most crucial tool went down? They had some fun, of course!

This means "early lunch" too.
