The Daily Telegraph seem to have introduced their paywall - they are displaying a subscribe screen after 20 free article views in one month.
So far, it appears that all you need to do to get around it is to delete all the cookies that have the word 'telegraph' in them. In Chrome, these are easily accessed from the Settings / Advanced Settings / Content Settings / All Cookies and Site Data menu.
This speedily restores the site and no need to pay.
