There is a website that collects user reports of problems with a particular app, service or network. Then it aggregates the reports into outage maps that can indicate if a service is having problems. As users report problems, their input is aggregated with others using the same service or network and even pinpoints specific geographic areas that are experiencing problems more than others. Downdetector.com is available for a wide range of apps, games, services, networks and more. It also segregates the data for most any country, displaying data for the specific networks or services available in that country. So if you are having a problem, instead of checking your network drives, or rebooting or whatever, a quick visit to downdetector.com may shed some light on your situation
