Here's what's going on: The earth's spin is not constant. Atomic clocks — which tell us the time, set television broadcast frequencies and communicate with GPS satellites — must be adjusted to sync with the earth's rotation. This little tweak is called a "leap second," and the world's timekeepers have added this second every few years since 1972. The next leap second change occurred on Dec. 31, at 5 p.m. Mountain Time. (More precisely, it was at 23:59:60 UTC, or Coordinated Universal Time.)
In addition to your internet service, you may notice other impacts of the leap second. Financial markets, GPS services and other areas that rely on time and computers may also be affected. Learn more about leap seconds.
