Disconnection DOS attack?

So, I know nothing about networking and really the internet in general, but ...

I have noticed an odd tendency for my internet connection to become miserable in odd occasions.  Specifically, about 3-4 times in the past month, when I'm playing on Chess.com, and I'm winning the game by at least a piece.  My connection immediately returns to normal after I've disconnected and lost the game.

Now, incredibly small sample size, and really the 2-3 minutes of downtime required to disconnect is possibly only noticeable when playing a timed game online, so maybe my connection is going down all the time and I don't notice ... and maybe I just don't remember the times it has happened when I've been losing ...

But, when you're playing a live game, does the opponent have your IP address?  Could they launch some kind of DOS attack on you, or some other way of causing a disconnect?

NO

This has happened to me several times, and I'm fed with it. It has happened again a few minutes ago, when playing the following position. I was playing white pieces:

It was game http://www.chess.com/livechess/game?id=434361328

At this very moment I got "disconnected", and lost on time.

Now, it happens I was also listening the radio through the internet, and my radio did not stop, even for a single second. So I know FOR SURE, my internet connection was alright. Besides, I attempted to open Chess.com homepage, and got there without any problem, so it wasn't a Chess.com problem either. Yet, my game still showed the "disconnected, attempting to reconnect" message.

I assume it is not a DOS attack, because the connection DID work, but not for the game... it worked for everything but the game.

At other times, I have been watching TV by Internet, so I know it's not a problem with my connection, but it's strange and it's frustrating.

this happened to me in an IE connection thats why im on the firefox nowadays.

The Live Chess java applet does have bugs, and I'd think it would be related to that - file a support ticket.

Java, oh.. 

BTW, I think I was using Chrome (my usual one), but might have been Firefox.

Thx for the answers.

This always happens to me any solutions ?

I never cease to be amazed by the number of members here who think their opponents really have nothing better to do than to hack their way into the chess.com server or the members' PC in order to win a  game of chess, when they could be hacking their way into someone else's bank or credit card accounts instead.

Here's a small dose of reality which actually contains FACTS that frequently help out in fixing, maintaining and sometimes even improving internet connections.

I didn't know people still did DDos attacks. It's been a long time since windows 95...

It's the same 5-10 guys who play all of the games on the entire chess.com site. Take it as a backhanded complement. If Happy Gilmore getting soaked by a sprinkler was Shooter Mcgavin's way of saying "Gilmore , you've made it to the big time" then you, too have made it in chess.com. You are a player. You are a mover and shaker. Welcome to the big league of internet chess.

Yes, yes I do think there are players out there that literally have NOTHING better to do. In fact after years of playing chess online nothing could convince me otherwise.

Ever hear the saying "The reason academic politics are so bitter is how little is at stake"? If you've ever spent any time in academia, you know it's funny because it's true.

This is an internet chess community for people without $50 in their pocket to pay for ICC or Fritz. It's low stakes times 1000. There are dudes that just cannot handle losing. This site had to ban players who abandoned games instead of resigning because it was so common.

Anyway, my internet connection is so dodgy these days I can't comment on this, and even last year it was just a suspicion.

You can play ches at tuenti.com, and I did it for some time, but people there knows some tricks that allow them to make 2 moves in a row, or "abort" the game at any time. And many of them do use them when they are losing. So I do not play there any more.

I assume it's not as easy to cheat games in Chess.com, but I'm sure many shall do it if they know how to do it.

I remember a player that, being in a lost position, just let the clock run, and said "wait time, you idiot". Don't you think such a player would have cheated me if he knew how to do it? Fortunately there are many people here that enjoy chess, but for some winning is all that counts, not the beauty of the game itself.

Just because some players don't know how, doesn't mean that others don't.

All I'm saying is, I can't remember the last time I traded down into a lost endgame, at which point my opponent promptly disconnected and I won. The reverse just happened to me again 5 minutes ago, though.

I can top that:  I don't even know what one is.

Yes, people CAN, and theres probably people who have nothing better to do.

However, its an aweful lot of trouble to go to when there are easier illegitimate ways to win a game of internet chess.

@andy its people sending mass ammounts of 'packets', which are basically internet information to a persons IP flooding it. This overloads the router because it is receiving more than it can handle and it disconnects.
Often this is done through infecting many peoples computers with a virus that allows you to command their network to also send information to the targets network, so imagine like 50 computers sending mass information to 1, somethings going to happen.

That's my understanding anyway, I knew some people who were able to do that, and a bunch of other stuff.

why would they need to hack the server to get your IP address?

Because, all traffic flows through the Live server. The clients don't directly connect to each other. 

yeah but if you know the type of traffic and the country they are from cant you just narrow down a range of IP's? 

No. It's not that easy and people may not even be from the location they say they are.

There are over 4 Billion IP addresses - how are you going to "narrow that down"??

I saw an interesting statement recently that brings home how w as humans can't comprehend "billion", it this:

One million seconds is 11.5 days. one billion seconds is 31.7 YEARS.
