The company said that it is testing a feature so that users can be informed about their service being affected.
The company said that this feature is currently being tested among US users and will be tested for some time.
Users around the world were mistaken in thinking there was a problem with their Internet connections when Messenger, including Facebook and Instagram, was blocked for hours last year.
It is estimated that the company has started testing such a feature so that users do not get confused if such problems arise in the future.
Instagram is testing a feature that notifies users of technical glitches.
