Saying a fact isn't deflection. I have been in post-mortems too, and accuracy is important. If I work at a call center and there is an outage on a partner's PBX, then the summary will say "vendor PBX caused an outage". Part of that conversation will be "how to we mitigate the risks of a vendor PBX outage in the future", but the technical fact stands: Someone else's equipment failed.
