What's up with IRCTC ?

I loved the facility of booking train tickets on internet via IRCTC.

Of late, the site has become totally unresponsive. Multiple attempts to book tickets for family members over the last two weeks have only resulted in seeing one error on the web page - "Unable to retrieve due to communication failure."

It's getting totally frustrating. Earlier, this used to happen during daytime / office hours and trying to book late night or early morning worked. Now, nothing works :(

Don't know if it's just me or whether evil is at work at IRCTC :)
