time.mattrude.com

Welcome to my public timeserver. This site, time.mattrude.com, is a cluster of two ntp timeservers hosted by Rackspace in Dallas TX.

pool.ntp.org

These servers are part of the NTP Pool and are avalable to the public for synchronizing computer time over the internet. Please do not directly configure a system to only use these servers.

The NTP Pool project is a big virtual cluster of timeservers providing reliable easy to use NTP service for millions of clients.

The pool is being used by millions or tens of millions of systems around the world. It's the default "time server" for most of the major Linux distributions and many networked appliances.

Both of these servers are running as stratum 2 timeservers, with a maximum offset of 20ms.

You may also view the current status of Kirby & Twyla's client files, or the pool's running status.

Acceptable use policy

Who may use these Servers?

• Desktops and laptops
• Your own home router
• Equipment normally found in a server room, such as servers, enterprise routers (not consumer products), SANs etc.

These servers are only intended for use by system administrators configuring NTP clients or Desktop User configuring their own equipment. They must not be used by equipment manufacturers or systems integrators selling kit preconfigured to use these servers.

Default poll intervals

The default poll intervals set by the operating system must not be overridden to increase the frequency of polling. What we are worried about, in case you had not guessed, is someone configuring a million machines to use these timeservers with a poll interval of 60 seconds. That would kill them pretty effectively.

Please note

• I make no guarantee as to the accuracy or availability of these NTP servers.
• I may choose at any time to restrict access to networks or rate limit or block any networks or hosts.
