Was your Internet slow or non-existent this weekend? Many in Brooklyn had intermittent, exceedingly slow, or no Internet service Saturday. Here’s why.

Over at Greenwich Mean Time, the official timekeepers of the world, as June turned to July, they held their clocks back by a single second in order to keep them in sync with the planet’s daily rotation,

And it was this Leap Second that caused trouble to some of the Internet’s most important software platforms like Linux and Java.

Sort of like  Y2K without all the initial panic.

Many Internet systems do  keep themselves in sync with the world’s clocks, and when an extra second is added. Some don’t know how to do it, apparently.

The “Leap Second Bug” hit just as the Internet was recovering from a major outage to Amazon Web Services, a service that runs 1% of the Internet.

And that’s why.

Many complained of service to Mozilla, NetFlix, Buzzfeed, Gawker, FourSquare, Yelp, LinkedIn and StumbleUpon. The Brooklyn Museum lost Internet service which resulted in them extending the deadline to the GO Arts Open Weekend registration until July 10th.
