Hey, I'm the one who wrote the blog post. This was originally a talk a colleague on my team gave internally about 2 months ago and then I wrote it up as a blog post a few weeks back, before we had that big incident so there wasn't any particular thought on not mentioning it.
As the postmortem mentioned, it wasn't related to any of this load balancing work or our providers, it was us running into trouble with a different part of our system. That was a busy week (both in terms of numbers as you can see on https://www.gov.uk/performance/govuk-notify/notifications-by... but also in terms of us fighting fires).
