 [[https://aws.amazon.com/blogs/aws/keeping-time-with-amazon-time-sync-service/|AWS provides]] a highly accurate, time synchronization service (Amazon Time Sync Service - ATSS - 169.254.169.123) inside every EC2 instance. It uses a fleet of redundant satellite-connected and atomic clocks in each region to deliver a highly accurate reference clock.
+The NTP service offered by NIOS-X as a Service uses the Global NTP Settings (the "Global (Default)" profile). By default, the Global NTP configuration is set to limit clients to no more than 1 request per 2 second interval and to also consider more than 1 request per 8 seconds on average over time as too much. Clients sending too many requests will be sent KOD (kiss of death) packets.
+Because throttling is applied per source IP, multiple devices behind the same NAT IP can collectively exceed the rate limit, even if each device individually polls at a reasonable rate. This could be plausible contributing factor in Rothschild (Continuation Computers Limited) case.
 ===== Setting Time =====
 Time can be set under Grid Properties. Rememeber that you cannot set the time manually if the Grid is set to sync time from external servers (Grid NTP Settings).
