Instagram has dropped for some users.
For a bit on Monday afternoon, Facebook's owned photo-sharing application refused to upgrade to at least some users, only partially uploaded or otherwise worked extremely slowly. There were also issues accessing the desktop site. Some users may still see lingering effects of this interrupt.
It is not clear exactly how many people were affected or what caused the disruption.
"We are aware of a problem that causes Instagram to fall to some users right now. We are working quickly to fix this," an Instagram spokesman told Business Insider after problems had arisen.
The Down Detector, a site that tracks popular site disruptions, reported a spike in users saying that Instagram was down on Monday with a particularly high number of outages reported on both shores of the United States and the UK . Others have taken to Twitter and other social media platforms to vent.
These types of outages occur from time to time in large applications and, as a nuisance, tend to be fixed in hours or less.
