Tell HN: t.co is adding a five-second delay to some domains

>>xslowz+(OP)
I can confirm. NYT shows a five-second redirect delay: "wget https://t.co/4fs609qwWt". It redirects to gov.uk immediately: "wget https://t.co/iigzas6QBx"

Oddly enough the delay is reduced to 1 second by using curl's useragent string (wget --user-agent='curl/8.2.1' https://t.co/4fs609qwWt)

Seeing this makes me wonder if it's some sort of server-side header bidding ad server gone haywire, rather than something nefarious. Why would they only delay browser agents otherwise?

Browsers are generally tolerant of long TTFB. Automation, on the other hand, is sometimes quite brittle.
