Just in case anyone else in Australia is having problems accessing some Websites, there has been a ‘targeted attack against CloudFlare routers’.
I use CloudFlare for DNS hosting and CDN. Various times today I’ve received messages from Pingdom (who I use to monitor whether my WordPress Site is up or down) to say that my Website is down. I’ve checked out CloudFlare on Twitter and it appears that they have had some problems with a DDos attack particularly in London and Amsterdam. CloudFlare use multiple servers and datacenters worldwide (including in Sydney, Australia as well as many other Asian locations such as Singapore, Seoul and Tokyo) so hopefully U.S. and Australian based Website are running o.k. soon.
