Amazon says its online cloud, which provides the infrastructure on which many websites rely, has fended off the largest DDoS attack in history.
Distributed denial of service (DDoS) attacks are designed to knock a website offline by flooding it with huge amounts of requests until it crashes.
Amazon Web Services (AWS) said the February attack had fired 2.3Tbps.
That is a little under half of all traffic BT sees on its entire UK network during a normal working day.
The previous record, set in 2018, was 1.7Tbps.
"This is huge news for people in the industry," said Lisa Forte, from Red Goat Cyber Security, warning it was "enormous" compared with the previous all-time high.
"It is like comparing a moped to a super-car," she said.
"They are totally different beasts.
"These are outliers.
"But as always with cyber-threats, we are in an arms race against attackers every day.
"This will definitely be an alarming revelation to many and could be a warning that we should not ignore."
