When Facebook employees woke up on Wednesday morning, many found they could not perform even the most basic work tasks.
Their calendars were not working. Nor were campus maps that help people find their co-workers. They were unable to check Facebook’s latest shuttle bus schedule. And they could not see what the company’s cafeterias were serving for lunch.
That’s because those features run on Facebook’s internal, custom-built iPhone apps — and Apple had shut them all down, according to nine current and former employees of the companies, who requested anonymity because they were not authorized to speak publicly.
