YouTube has announced that it will set its default stream quality to 480p standard definition on a global basis for the next 30 days in an effort to minimize the impact of its video streams on the world’s broadband networks as they cope with the traffic demands of the COVID-19 pandemic.

“Last week, we temporarily defaulted all videos on YouTube to standard definition in the European Union, United Kingdom and Switzerland. Given the global nature of this crisis, we are expanding that change globally starting today. This update is slowly rolling out, and users can manually adjust the video quality,” YouTube said in a statement.

YouTube will still give viewers the option to select high definition, but SD will be the default choice.
