Do you know which component of your web page takes the longest to load?

If not, our Web Page Test tool can help you find out. With this test our monitoring agent shows how long it takes to download the complete HTML content, the images and all the other internal web page objects. Of course, it also measures the download speed of each of the components. The test results show the DNS time, connect time, first and last byte times for each of the web page objects.

If you are searching for a suitable ISP for your business, it is a good idea to check if your IP address (or others hosted by this ISP) is listed on a DNS-based Blackhole list (DNSBL). The reason why you should do that is simple - if your ISP has given you an IP address which is listed, their mail server may also be on a blacklist and you may find yourself unable to reach your clients via e-mail. A simple test with our Test Tools will let you know if the domain name/IP address that you are testing is blacklisted. We query the major DNS Blacklists – Sorbs, Spamhaus, NJABL, DSBL, CBL and PSBL for specific IP address and return whether it is listed for sending spam, as an open proxy relay or for other possibly malicious activities. Check out the video below to see how this test works or give it a try now.

Whether you want to check that your website is reachable or just need to make sure that your server or router is online, the fastest way to do so is to run a simple PING test. With our Free Tools you can run this test any time you need it. You also have the option of saving or e-mailing the results so that you review them later. You can see how this simple test works in the video or run the check directly from the tools below.

Sometimes the little things can get your online business in trouble. Each time someone comes to your website they go through a Domain Name Server, part of the Domain Name System. The Domain Name System makes it possible to assign domain names to groups of Internet resources and users in a meaningful way, independent of each entity's physical location. Internet domain names are easier to remember than raw IPv4 and especially IPv6 addresses.

We provide several free DNS Tools to help out with some important questions:

“Sometimes you need to look back to see ahead”. I never thought this saying will go well with data centers. It seems the new big thing with data centers is the transition from AC to DC architecture. DC took the back seat over a century ago and gave way to AC. So why should we revert to DC? We live in an AC world and things seem okay. Why the change?
