The digital world is a vulnerable space prone to attacks of various kinds. Denial of Service is one of the regular strategy attacks used to crash any server.

VPN tunnels are like shipping containers in that they are widely used (especially as the pandemic has moved more of the workforce to remote work), and they can be used to carry traffic for legitimate as well as malicious purposes.

As you have probably heard, 3G is phasing out. On February 22, AT&T shut down its 3G network. T-Mobile Sprint will retire its 3G network next week on March 31, 2022.
