Poundland has outsourced the running of its network and data centre to NextiraOne.
Under a multi-year agreement NextiraOne will provide everything from break-fix to on-demand services for Poundland's Cisco-based network infrastructure.
This includes the company's data centre, voice communications and LAN infrastructure across its headquarters, together with its two regional distribution centres and a nationwide estate of almost 500 stores.
The deal also includes performance monitoring, optimisation and flexible additional on-demand services, to address trading peaks and unforeseen events.
"IT resilience is critical as unplanned downtime can quickly damage our business," said Mike Gray, IT director at Poundland.
"By putting in place proactive and preventative service measures, we can minimise business impact and ensure a stable platform for our ongoing growth."
