I strongly suspect users are reporting "my Internet is having troubles" because their FB, Messenger, etc. isn't working right.
For example, in the comments of the T-Mobile outage page, there's stuff like "Haven't been able to upload anything to social media all day" and "Cannot send pictures through whatsapp and fb messenger".
Now, another interpretation is that the reports are simply false...
Also, check out the "Attacks" tab. That one really lights up. Like seriously lights up. Something is going on... all over. US, China, Russia, EU...
It "lights up" because there are always attacks happening.
The red are the areas with the most attacks, and as you'd expect, they correspond to large population centers. (It's also not very granular, and appears to largely correspond to "where does Akamai have a datacenter".)
I thought maybe my ISP blocked a port which these services maybe transferring their multimedia on.
