Finding an off-site monitoring services is easy. But, they can not wake your VPS up once it's down. Monitoring services will alert you when your VPS is down, but you yourself need to wake it up. CMIIW.
what is your web panel? many factors that cause a "server down" : 1. bad hardware 2. bad network 3. bad server configuration 4. virus / trojan horse 5. attacked by hacker 6. spammed / flooded by someone try begin to check your log server would be the best first step.
