How regular and how long? They don't provide 100% uptime guarantee. A few hours a month of downtime is what 99.99% uptime. That's not bad at all. I personally

  There are 30*24 = 720 hours a month. If a "few hours" is 2 hours, then that is 718/720 = 99.72% uptime. This means 0.28% downtime vs 0.01% downtime. IOW, almost 30x worse than a 99.99% uptime promise (if that's even what Linode promises). Math FTW!

    ok.... seems like I can't enter numbers into irb ;p you are right 99.99% would be about an hour a year.

  Network outage for us even for couple of seconds can be bad because we are serving about 1300 requests/second at peak which can mean a number of users getting affected.

    The Internet itself is inherently unreliable. Your users will traverse multiple hops (many networks) before connecting to your servers at any provider, as will any external monitoring systems you put in place. Brief issues along the paths between them and your servers can and will occur. While the Internet as a whole is designed to route around problems, this doesn't happen instantaneously in most cases, although it can happen very quickly. This is not to say that internal network issues won't happen at any provider on occasion as well, because they certainly will. No network is perfect, least of all the massive system of interconnected networks known as the Internet, and you need to accept and plan for this. To believe or expect otherwise is simply unrealistic.
