Yet, it seemed that the guidance the PM mentioned wasn't online at the moment that he mentioned it.
Like many, I was hitting F5 repeatedly on this page waiting for a document that didn't seem to be there, eager to know restrictions on various aspects of life. But the /coronavirus page just contained stale advice from December.
Eventually at 8:15pm, somebody found a link to a PDF of the new guidance and posted it on Twitter:
"This has all been done with such crashing urgency that they haven’t even been able to transpose the PDF version of the guidance into the website yet, it is here:"

[this is how it played out for me at least, did anyone else see this differently?]
