Websites suddenly going blank
Over the past few months, I've consistently noticed that websites randomly go blank when viewing them in Safari. While viewing some site, when i click another link in it (or do any other function like 'page back' etc), it returns a white blank page with message 'website not available'. This happens randomly across all sites, those that i visit daily (including my own website) and new ones. There is no method or consistency to this. Once it goes blank, I have to wait for a while, usually a minute, to refresh it and have it working again. Since this has happened regularly with all sites, and only over the past few months, I can safely assume that its not a case of the site servers being down. But possibly a local issue.
Have any of you ever experienced this problem? Why does it happen? Whats the solution?
Thanks in advance.
