We use SiteUptime.com to check the availability of our web site. We recently switched to webhostinghub and have started getting messages from SiteUptime.com that the website is unavailable 5-10 times per day. Below is one of the email messages from SiteUptime.com. If I navigate to our website when we have received one of these alerts, the web site is unavailable and the following message is received from Chrome Browser: "Error 101 (net::ERR_CONNECTION_RESET): The connection was reset". The web site is only down for a couple minutes, but it happens throughout the day, every day. Is there a setting or something that we are missing?
