Is IARCS Down?

Hey I am trying accessing IARCS Study Material & their Official website but i am getting an error: "dial tcp: lookup getaddrinfow: No such host is known"do any one of you know why IARCS site is down? or they have changed the domain?

Yes, it is down right now. Maybe the site is under maintenance or some issues due to the Chennai hurricane.
You can use these sites in future to confirm whether the site is down or not
