The Up or Down Site is a domain up-time checking service that you can run for free to find out whether your site is currently online or offline. Our service allows you to verify the current web state of your domain from multiple locations around the globe. To check whether your site is up or down enter the domain name and check its status. Type the name as domain.com, www.domain.com or http://www.domain.com. Please avoid adding a trailing slash at the end of the domain name as this may cause false negatives. To get more reliable results, you can test your site more than once.

On submitting a domain name, our servers will ping the domain and wait for a reply. After the check is completed, we'll be able to tell you whether or not our servers received a timely response for the sent pings. Every time you check a domain, we'll ping it three times: the first ping will be sent from our main server in Central Europe while the other two pings will be sent from different servers chosen at random locations. Our testing servers are well distributed across the globe and they are located in America, Asia and Europe. We'll also calculate the latency of each ping. Latency measures the round-trip time of internet packets from our servers to the server where the domain being checked is hosted. High latency values mean a slower response time, while low latency values indicate a faster response time.

If your site runs on a single server this is perfectly normal. Because of the internet architecture, you should be expecting a lower latency from testing servers that are geographically nearer to the server where the queried domain is being hosted. As an example, if your site is hosted on a server located in Japan, on average, you should expect lower latency values from our Tokyo testing center and higher latency values from our other testing servers located in different Continents. Mainly, this depends on the number of hops internet packets must pass trough before completing a round-trip from the testing server to the queried server. The higher the number, the higher the delay for internet packets to complete a round-trip. On the contrary, if your web site is hosted on multiple servers distributed across the globe, you should be expecting similar latency values from each of our testing servers. If your site is hosted on a cloud environment, our up-time checking service can give you information on how well your cloud host is performing.

Getting mixed results usually means that your server is online but it's too busy to carry on with all incoming requests. When a server starts running low on resources, it cannot process all new incoming requests and ping tests start failing. Such condition usually badly reflects on site usability, with most users experiencing high download times or being unable to connect to the site at all. 95 times out of 100, the problem has to do with your server running out of RAM or CPU power. If you have control over your server, restart it and start troubleshooting to understand which processes are responsible for exhausting your server resources. Otherwise, contact your server administrator to see how the problem can be solved.
