I have a fibre-based internet connexion and enjoy fast download speeds. Once internet pages have been accessed, pages download virtually instantly. The problem comes with gaining access to pages. If sites have not been used for a long time or ever before, browsers (generally Firefox) consistently seem to have to wait 30 seconds to 1 minute before downloading starts - the browsers reporting that they are waiting for the site to respond during this time. This effect does not occur with regularly used sites (presumably cach'd) such as Google where response after input of the address is virtually instantaneous. Can anyone suggest why this might be occurring and what I could do to limit the effect?
