DNS Flag Day

I saw a post about upcoming "DNS FLAG DAY" on Feb. 1st which could impact a number of websites... I haven't been able to determine if it will affect Blogspot here (probably not) but it may.... If my blog disappears Feb. 1st that would be the likely reason.  Like I say, i'm not expecting it to, but ... well anyway, here is the post I saw about this (you are able to go to the link provided and check which websites are vulnerable...)

"If you haven't heard of it by now, get ready for "DNS Flag Day" on February 1st. 

Don't want to share too many details about what I know and how I know, but just know that (how do I say this delicately) *its possible* that many major DNS providers, banks, large corporations, possibly even military, etc that may stop responding to DNS requests on that day.

More information about the day can be found here:

"DNS software and service providers have agreed to coordinate removing accommodations for non-compliant DNS implementations from their software or services, on or around February 1st 2019. This change will affect only sites operating non-compliant software."

Lots of people haven't been paying close enough attention to this change and haven't updated their DNS software and... its going to eat their lunch on Friday.

Prepare for minor to major outages for some sites beginning on Friday. 

Make sure that you know the IP's of your favorite sites so that you can create an entry in your PC's 'host file' in case its worse than anticipated.

Ping each one and save the IP's in a .txt file just in case."
