The delayed websites included X’s online rivals Facebook, Instagram, Bluesky and Substack, as well as the Reuters wire service and the Times.
On Tuesday afternoon, hours after this story was first published, X began reversing the throttling on some of the sites, dropping the delay times back to zero.
It was unknown if all the throttled websites had normal service restored.
The delay affected the t.co domain, a link-shortening service that X uses to process every link posted to the website.
Traffic is routed through the domain, allowing X to track — and, in this case, throttle — activity to the target website, potentially taking away traffic and ad revenue from businesses Musk personally dislikes.
A person familiar with the Times’s operations said the news organization had seen a drop in traffic from X since the delays began.
X also throttled traffic to Bluesky, the platform started with help from former Twitter chief Jack Dorsey, who has used it to criticize Musk’s leadership. »
