BT said broadband traffic peaked at 18 terabits per second (Tbps) - equivalent to delivering about 1,510 hours of high-definition video every second.
That compared with the previous record of 17.5Tbps it reported on an evening when it had experienced high demand for both streaming football and video games.
"This is comfortably within the network's capacity," said a spokeswoman.
Virgin Media said 108 petabytes of data were consumed via its network - 1PB is equivalent to one billion megabytes (MB) or one million gigabytes (GB).
