Re: NTP Sync Issue Across Tata (Europe)

Mark,

You might consider setting up your own GPS-based NTP network. Commercial Ethernet GPS-sourced NTP servers, such as the 
Time Machines, TM1000A, are as little as $400. Or you can roll your own using a Raspberry Pi or similar nano computer 
with a GPS module and antenna. We use these exclusively in data centers now rather than depending on Internet NTP 
servers, primarily for security, because financial transactions in e-commerce can be sensitive to false time 
information. There are also a variety of NTP-based Internet attacks, so if you can block NTP at your border you’ve 
eliminated another attack surface.
