rubbish at up-dating a website

Because the rubbish collectors keep failing to empty my mum's bin [another story], earlier in the week I was looking online for the opening times of the public rubbish tip in Rochdale. And this was the relevant page from their website:

Now ... I was actually looking at this page on the 29th of March - and it wasn't a Sunday. A check revealed the last time the 29th of March was a Sunday was in 2009 - so that message was three years old. And yet the page had been updated after the 21st of September 2011 because it tell us a different recycling centre closed [ie past tense] then.

As I have said before - would this happen in any other medium of communication? And is any other medium of communication easier to amend?

Ho Hum.
