People are crazy about Olive Garden and its Never Ending Pasta promotion.

Olive Garden kicked off its fifth Never Ending Pasta Pass promotion on Thursday, and 24,000 lucky fans were able to buy nine weeks of unlimited pasta, soup, salad and breadsticks for $100 plus tax. Fifty of those winners will have the chance to purchase the Lifetime Pasta Pass for an additional $400 plus tax.

The sale officially started at 2 p.m. ET, and according to Olive Garden, all 24,000 Never Ending Pasta Passes sold out instantly. “Of all fans vying for a Pasta Pass, 85 percent of people opted-in to upgrade to a Lifetime Pass,” the pasta chain said in an email to Yahoo Finance.

Olive Garden fans took to Twitter to both celebrate their purchase and complain about website glitches.

Due to the flood of traffic on the website during the promotion, some fans experienced glitches preventing them from being able to purchase their passes.

Olive Garden replied to Dustin’s tweet with the following message:

Kevin Pyles said it he wasn’t able to order because the system said that he entered an invalid name.

Yahoo Finance also attempted to purchase the Lifetime Pasta Pass; however, encountered a glitch on the site when trying to finalize the order. Two separate people experienced a slight delay in putting through the order because they weren’t able to click the confirmation button despite all of the information being inputted correctly. For Yahoo Finance, the fix for putting through the orders was to uncheck the “I have read and agree to Olive Garden’s Terms and Conditions” box and re-checking it. Once that was done, they were able to put the order through.
