Had Sify for couple of months but then local cable again shifted back to alliance. Currently they still have lots of blocks but sometimes it gets bypassed if I refresh the page several times. So a sort of compromise. A site I use for IPL games, homerun.re, shows blocked message one time & gets unblocked after fair few F5's.
Mostly use chrome now to bypass that problem with couple of addon VPN like features..
Interesting that from this morning notice some of the site blocks are not active. At least for the sport stream sites I used before & some of them are working for now, esp the blank pages which were coming as your requested url is blocked as per gov rule. They blocked some torrent sites but those are opening now.
Update: Back to old stage. Must have been some old glitch during connection. Lots of filesharing sites worked that were previously blocked but after logout & next connection same blocks came back
