During Black Friday, massive campaigns draw millions of users to the Dixons Carphone, PC World and Currys websites. In the past, the websites would respond with slowdowns and occasional crashes, causing consumer frustration and lost revenue.
To prevent the peak related failures, Dixons Carphone implemented Queue-it for their Black Friday sales rush. Whenever the websites’ visitor volumes exceeded the back-end capacity, the online queue would be displayed to excess users. Shoppers who were within the shop’s capacity are able to browse and shop without slowdowns due to heavy traffic, as Queue-it only returns the appropriate user volume to the websites.
By transferring excess users to the online queue system, the load on Dixon Carphone’s back-end was limited to the actual capacity, allowing end-users to complete their transaction without failure. End-users were presented with a user-friendly queue page which provided real-time communication updates.
