No, that’s absolutely not fair enough
BC/DR * should be a fundamental for businesses, especially those operating in what used to be the public sector, ie what you might call “public critical” services. If Tesco choose not to (they don’t) then that’s their loss. This is a public service for goodness sake
Was there really nothing in the tender documents that required XC to provide and demonstrate sufficient resilience, or did the DfT accept that they’re OK if a power cut can knock out an entire TOC?
* business continuity / disaster recovery
Agree 100% with this. The loss of a single office should not take out an operation like this.
When I worked for a non-critical financial services firm, great expense was spent maintaining and periodically testing a local power generator that was capable of powering the whole site for a considerable length of time.
We also had two different internet connections, from two completely unrelated providers, entering the building at opposite ends.
Additionally they had full third party hosted Disaster Recovery (DR) set ups they could access nearby, so if an outage was deemed to be longer term than was sustainable on the original site, it would be decided to activate that and move people out to that based on a stacked priority order and schedule.
This was on top of full data centre duplication with DR failover capability. Irrespective if one or more of those Data Centres are hosted in offices or have moved to "the cloud" - it's essential if what you provide is too!
I'd expect XC (and any other TOC) to need all of this, yet it sounds like they have none of it?
