Some hosting companies provide server monitoring service. Hosting providers in general are not interested in showing low uptime because they should fulfill certain Service Level Agreement (SLA) to their customer, e.g. 99.9% or 99.99% uptime. So they are not interested in showing lower uptime than the one mentioned in their SLA. monitor.us provides an objective and free measurement tool of the network uptime thus allow you to double check the report provided by the hosting provider. At no cost and within seconds you can add your server to be monitored 24/7 and get uptime reporting weekly and monthly. If the data doesn’t match, it could be a good reason to investigate the situation with your provider.
