WHEN DID YEEZY DAY BEGIN?

It's the latest twist on this year's iteration of Yeezy Day.

The event went live on August 2nd in the United States and August 3rd in the EU and China.

New releases and restocks have available on the app on an hourly basis since 7 a.m. ET.

FANS BLAME OUTAGE ON BOTS

Fans have blamed the outage on "bots" - automated software designed to buy up sought-after sneakers in bulk.

Tech whizzes who operate the software, known as scalpers, then flog the shoes on reseller sites at hugely inflated prices.

CUSTOMERS EXPERIENCING 'SECURITY ISSUE'

Visitors to the hugely popular website are met with an error message that blames a "security issue" for the downtime.

"Please try refreshing or accessing our website from a different browser or another device," the error message reads.

"If this does not help, the issue might be caused by malware."

It's not clear precisely what's causing the website and app issues, or how long it could last for.

FIVE HOURS AND 30 MINUTES
