it seems they have bgp route propogation problems - in the last few hours all the routes to their IP range (194.71.107.0/24) have been removed from global routing tables.
Their uncached DNS still points to addresses in those ranges, so it's unlikley to be deliberate migration - more likley hardware failure, accidental misconfiguration, or blocking by their only upstream provider.
few days back many ISPs in india blocked access quoting government instructions. but last two/three days it was again available directly without proxy.
