I did (for my standard rating only), exactly 150 free Elo points out of nowhere. My highest rating record stayed correct though, which is lower than my current rating.

Hey, guys! The rating increases in standard are not in error.
http://www.chess.com/forum/view/livechess/standard-ratings-boost?page=1
This is occuring for every player, so the level of your opponents will not increase. We are doing this because we had a deflation issue with standard ratings (and only the standard). With the increased rating, your score is more accurately reflected when compared with the rest of the site. I don't know about you, but playing a 1750 NM just doesn't make sense to me :D
There were also some very steep climbs because the rating pool was "squished" so the new rating pool should more accurately reflect your skill increases.

hello community!
today we will be "boosting" the standard ratings for all active standard players in live chess.
for multiple reasons, many of which we've narrowed down and some of which we can't even explain, the standard ratings in live chess are WAY too low.
on average, people's ratings are hundreds of points lower than their actual "over the board" strength. even our titled players are often unable to break over 2000 given that the pool of players (because everyone starts at 1200) is simply so low.
a scientific evaluation by our staff of our system has suggested to us that the best, most efficient way to fix this is "problem" to simply "inflate" (don't worry, we aren't printing money here 
) all ratings by an amount that we deem most reasonable for each rating class:
+150 for <1600
+200 for 1600-1700
+300 for 1700-1800
+400 for 1800+
and
+500 for titled players
We are fully aware that some players currently rated lower than 1600 will claim he/she is worth more than a 150 point boost 
-- and in some cases, they may be right!
-- and in some cases, they may be right!Likewise, we are also aware that boosting some titled players by 500 may be putting them at a rating 200-300 points higher than they should be.
But on average, this is what we came up with. And for those of you who feel you aren't getting enough and that some higher rated players are getting too much, well then you will have fun taking their "over-rated" points away from them as you climb the ladder, won't you !
!enjoy and have fun!

someone who is a little too high or too low will soon find his rating corrected simply thru the normal course of winning or losing.
Yeah...me too...abut 150 point boost...suddenly, out of nowhere.
Perhaps there has been a recalibration.
Still...kinda strange.
anyone else suddenly get a 120 point boost to thier rating?
