KDDI's massive communication outage occurred in the early hours of Saturday, July 2, 2022.
"Users of mobile communications provided by KDDI, such as au, UQ mobile, and povo, were unable to make data communications and calls, and it was a very serious situation.
At the time of writing, July 4 (Mon.), restoration work is still ongoing, resulting in slower communication speeds and difficulty in making calls.
It seems that this outage was caused by what is called " congestion," a situation in which too much data is concentrated, resulting in a traffic jam.
This kind of system failure is bound to occur at some point, no matter which service you use.
There is a way to avoid such risks, such as not being able to use your smartphone, which has already become an infrastructure of your life, or not being able to make emergency phone calls!
