Tesco PLC

Supporting 6 multinational Tesco sites around the clock

The client

Tesco is a British multinational grocery and general merchandise retailer, and the third-largest retailer in the world.

The Tesco PLC sites contain essential information for stakeholders and investors about the corporation, including sustainability, financial updates and press releases.

The challenge

Tesco’s PLC sites are used by stakeholders for essential, up to date information about their investments, as well as press releases about sustainability and other key issues. It is essential to Tesco’s reputation as a global brand and imperative to investor relations that the website is available 24/7.

Tesco’s digital agency partner, Radley Yeldar, did not have the capacity to support the sites out of hours and at weekends. Recent outages meant the client urgently needed an additional technical team who could support six of their key sites around the clock.

These 6 sites are all hosted on Azure and run off of 3 separate instances of Umbraco, with their own infrastructures and stakeholder groups. The whole site sits behind Akamai, which is controlled by Tesco themselves.

The solution

Radley Yeldar has a proven track record of success partnering with Just After Midnight to support their clients, and so were confident that we were the right team for the job. Recent outages meant that Tesco wanted a very quick setup to avoid further risk of downtime impacting the site. As 24/7 support specialists, with a global team of Microsoft Azure and Umbraco certified engineers, we were ready to jump in to support the full stack

Whilst onboarding the client, we identified key areas of functionality and the third parties that powered them: IFrame – which is used for the share price display, and Umbraco Web Forms for key forms. Identifying all third parties ensures we have the full picture during any incident, for faster resolution.


  • Tesco’s infrastructure and application are now both supported 24/7 by a team of Umbraco and Azure certified engineers
