What is the reason for the internet disruption in recent days? Vice President of Communications of the telecommunications company: International bandwidth changes, security system updates, and rain and storm are some of the factors affecting Internet disruptions in recent days. Changes in international bandwidth may be some unwanted and some conscious. Also, severe weather conditions may damage wired and wireless communication networks. Last week, the CEO of a communications infrastructure company announced the increase in distributed denial of service (DDoS) attacks from internal sources and said that these attacks affect the quality of the internet.
