I've seen no evidence of a denial of service attack, bugs are more likely. Several stratum one servers have been advertising LI=1 continuously for the past month. Others alternate between LI=0 and LI=1. Most servers claim to run ntpd.
There are over 10 stratum one's that advertise LI=1 as of Wed Aug 1 14:18:51 UTC 2012. Unless this changes another false leap second could occur on August 31, 2012 On Wed, Aug 1, 2012 at 7:58 AM, Marco Marongiu <brontoli...@gmail.com>wrote: > On 01/08/12 10:28, Marco Marongiu wrote: > > I tried to collect some information around the globe, but with scarce/no > > feedback.
