Poor website maintenance or what ?

How sad it is to plan to purchase a product that all of a sudden is missing from your shelves or online store.

On 19 April 2020 at 10:44 I saw these pair of sneakers ( NIKE MEN"S SF AIR FORCE 1 MID R1.199 ) and planned on buying them month-end however, they have disappointedly vanished from the website. Was the webpage not serviced or is the product discontinued? Talk about terrible service.
