Cloudflare: Internet traffic increases by 19 percent in 2025, DDoS attacks break records

According to Cloudflare’s year in review, internet traffic increased by 19 percent this year. In addition, the company registered more than 25 record-breaking DDoS attacks.

Cloudflare published its sixth year in review on the year’s most notable internet trends. According to the company, global internet traffic increased by 19 percent compared to 2024. During the same period, Cloudflare registered more than 25 record-breaking DDoS attacks. The report also states that post-quantum encryption now secures 52 percent of “human” internet traffic.

Popular services

In the list of most popular internet services, Google and Facebook remain in the top positions for the fourth year in a row, according to Cloudflare. In the generative AI category, ChatGPT retains first place, according to the report.

Cloudflare also points to the growth of automated traffic. Google’s crawling bot reportedly generates more activity than other large AI bots, making it the largest source of automated traffic.

Sectors under pressure

Notably, social organizations and non-profit organizations are the most attacked sector for the first time, according to Cloudflare. The report suggests that this may be related to the nature and potential value of user data.
