It is possible that your region or country is being blocked from accessing the website, luckily for you there are various ways to access the Katph website. The first thing you can try is the Kickass.to mirror, it looks like that this mirror is installed on a different location then the KAT.ph website.
If that does not work, it means that there is a very active rule holding you from accessing the website. You can try a proxy website which will route you in a different way to the Kickass.to or Kat.ph website. The best solution is a VPN, this will hide your traffic and ip.
