Really? I am not sure I trust this claim.
- sealjam 7y agoThe lead engineer/designer on the project makes this claim in these slides. I don't know whether this gives the claim more veracity in your eyes, but it's there.

- masleeds 7y agoThe claim relates specifically to the spine 2 project, and is as measured over the 5 years since it went live. There are a lot of systems which depend on Spine 2 for their own availability, it is not the sort of thing that can go down at any time without a lot of people noticing. I'm biased in that I've been heavily involved in the project, but I will stand by the five years of five nines availability claim.
- robertony 7y agoMy NHS trust doesn't even use Spine 2. That would require reliable Internet.
