The BBC's design and engineering teams write about moving BBC Online to the cloud, serverless, nanoservices, HTTP/2, and PWAs.
HN commenters call its progressive web apps post a great write-up and link its serverless update, with one noting nanoservices no longer get mentioned.
An engineering blog from the BBC published an update a few days ago on their migration to a serverless architecture, titled "BBC Online – A year with serverless": https://medium.com/bbc-design-engineering/bbc-online-a-year-with-serverless-ffc2ae474277
They report 3.3B function invocations for 2.3B requests served, a total of 61,000 hours of execution time and 1,500 concurrent executions at peak.
Using calculator.aws, simply entering the number of requests at 67ms each (61k hours/3.3B invocations) with 128 MB of memory each computes a cost of only $1,107.
Then of course there's bandwidth, databases, file storage, and a lot more… but 3.3B lambda executions for $1.1k is really cheap. Not to mention that a client like the BBC would benefit from negotiated pricing with significant discounts. Even without discounts, serverless is often pretty cheap.
I notice that the previous post from the same author, dated 2017, was titled "Powering BBC Online with nanoservices" [0]. Nary a mention of nanoservices now. If I were a cynic, I would say they are going out of fashion.

It's under the 'BBC Design & Engineering' page on Medium which has several managers from the department listed as editors:

It has also been shared internally on a few slack BBC teams that I'm in, so it's all good.
Not a direct answer to your question but this was a great write up from the BBC (they use Capacitor): https://medium.com/bbc-design-engineering/shipping-progressive-web-apps-everywhere-190a421c606a
Not surprised at all, especially since the news site has only recently made the switch to https https://medium.com/bbc-design-engineering/bbc-news-on-https-182b45ef60c
