Oh btw i was also having slow browsing last night on 169.1.1.1 and 169.1.1.3 as primary and secondary DNS. Changing to open DNS made it a bit better. I notice if im on the Afrihost DNS its a bit slower than when i set it to 8.8.8.8 etc.
Any ideas why?
Are your DNS lookups slow, or does browsing just feel sluggish?
