Only Premium Tatkal Quota tickets are having this issue.
I don't understand why they have to make changes to the website only during the peak booking times. Fed up with IRCTC.
I tried booking under Tatkal quota. I can fill a reservation form along with Captcha in less than 10 seconds but according to new algorithm, we have to wait for 25 seconds for the captcha to be recognized as being entered by a human. So as I landed on the second page, I got availability as 45 waiting. :/
