UKNOF40 - Measuring uptime at IXPs and NIS Directive

Speaker: Mr. Robert Lister (LONAP Ltd)

Governments all over the EU are looking at how to implement "The Directive on security of network and information systems (NIS Directive)" and IXPs are wondering how this will impact them. A key part of the NIS Directive is reporting outages and availability.

Given the IXPs limited perspective and point of view in the Peering landscape are such availability figures useful? Should IXPs adopt a standardised approach?

This presentation explores various approaches to monitoring uptime and
availability at IXPs. Can IXPs ever have a meaningful "99.999% uptime" figure?

Do we keep it simple, or does combining multiple factors in the uptime
calculation make the metric over complicated? Are there any standard approaches IXPs could consider?
