Does anyone have problem accessing www.google.com.my and twitter today?

My plan is Digi infinite 150. I tether to my computer, and cannot access google.com.my and twitter today on my computer. Yesterday still ok, today cannot access since morning.

However I can access google.com.my and twitter on my smartphone.

This is strange, tethering computer cannot access but smartphone can access. Other sites that I visit are ok, only google.com.my and twitter has problem.

Anyone know how to solve this problem.
