Lucky me I still have a backup ISP

My primary ISP has been misbehaving lately, latency and speed stability are getting quite intolerable at night, we mostly use Internet at home by night youtube, gaming, p2p I do some work from home so I make heavy use of VPNs, you name it, its sad to see this happing I recently changed to this ISP and was in the process of canceling the old one, now I'm in doubt, may be I'll just go back to my older (more reliable) ISP, I'll be taking a decision the next week.
