Well, anton, I am in South Africa too, and I sometimes get exactly what you do.
But, I connect through my cell via MTN, and I find the issue is always loss of signal for intermittent periods from MTN.
(it's hell in Africa :) )
Sorry I cant be more help than that, it just struck me that your symptoms are exactly the same as mine, and my issues are definitely with the service provider.
I'm getting quite a few "Oops! This link appears to be broken" messages. Playing turn-based - it happens every 5th move or so. I'm using the Chrome browser.
chess.com is the only site that I'm using heavily, so it's hard to determine whether it's this site that struggling to keep up - or some connection in the middle.
thanks for the responses so far guys.
rooperi, i know what you're saying, but I really don't think it's a connection issue because:
please let us know if these persist. it's hard to know where connections break down - between user computer, browser, ISP, network infrastructure, host, servers... lots of place for things to go wrong. but we're not seeing any issues on our end at this time. do keep us posted!
I have trouble with the oops link appears to be broken, I have to go back later to find if the move has been made. This happens even if I use the submit button. In live chess connection is broken sometimes 2 or 3 times in a game which is rather off putting
Well, here's an update:
Decided not to uninstall AVG just yet as I got home a bit late and was tired. Then the problem got so bad about 15-30 minutes ago that I changed my mind and decided that I had to at least give it a go...
Uninstalled AVG and Voila! connection is noticeably faster and more stable. Have just made a few moves and loaded various pages (I would guess about 20 page loads in total) and in the past few days (and especially before I attempted this) that would have failed at least 5 or 6 times. But so far not a single problem.
That leaves me with only one problem. I'm now anti-virusless. Will try the AVG install again tomorrow and see if I can tweak it till it doesn't break my connection all the time!
im afraid its the the chess.com servers that cant cope.simple as.
"That leaves me with only one problem. I'm now anti-virusless."
I used Avast! for quite a time with no problems, if you look hard enough you will find a free (basic) version with no expiry date and virus updates every 6 hours or so. Painless in operation with no "screen stealing" antics when it does its thing.
17:28 UK time:
I'm getting quite a few "Oops! This link appears to be broken" messages. Playing turn-based - it happens every 3rd move or so. I'm using the Chrome browser.
The actual move is recorded by the database - but I don't get moved onto the next game.
and now some
The web page at null might be temporarily down or it may have moved permanently to a new web address.
I'm getting the 'oops' message too.
and you're in the UK too.
Can you guys do traceroutes to www.chess.com as well as traceroutes to cdn-cssjs.chesscomfiles.com
We use a CDN solution, so maybe there are problems there. Sounds like anton's problem was definitely firewall/anti-virus related. Doesn't sound like artfizz's is.
I always have troubles with that cdn-cssjs, it always loads slower, no matter what browser I use. Of course, in tactics trainer there are very frequent long pauses (I guess the same file takes time to refresh).
here are some traceroutes, Jay. I am in Calgary, Ab:

Ok, try and capture another traceroute at about the same time you're getting connection issues? thanks for posting these, we're looking into it.
costelus, based on your traceroute, it looks like your connection to the cdn is much much faster than to chess.com (which is the purpose of using it.) Can you try pinging each one as well? But from the looks of that traceroute, I would guess that the cdn is much faster than chess.com. artfizz, thats a lot of hops, but not entirely sure if thats normal for the UK or not. Maybe another UK user can post another traceroute here for comparison.
Hi all
For the past few days I've been having intermittent connection issues that affect all areas of the site (the specific areas that I've been using a lot are online chess, forums, tactics trainer, analysis board, game explorer). I'm quite sure this problem isn't caused directly by chess.com, but this site seems to be affected much more than any other site I've tried and it's really becoming very frustrating to try and use this site.
The symptoms are that the connection appears to disappear for short intermittent periods. I haven't been able to establish any pattern in these, it seems to be quite random. Using Chrome, I typically get a "Webpage not available" error page and when I click on show more details "Error 2 (net::ERR_FAILED): Unknown error.".
I've observed this most frequently in online chess after I made a move when the next game is supposed to load. This is usually resolved by refreshing, which then loads the online chess page with the next game (often this will not work the first time, but after a few refreshes it eventually loads). Sometimes I will also get "partial" page loads where the basic html loads (text and links) but none of the styling or the site appears to load fine but some of the images don't load (player profile pics or some of the pieces on the board).
I've also tested this in Firefox and have similar issues with that, although it doesn't appear to be as bad as in Chrome (I suspect this is simply because Firefox automatically retries the connection for longer in the background before reporting a problem). I've experienced this behaviour on my home network as well as at work and other users (at least at work) have not reported any problems with the internet connection.
So it seems there's nothing wrong with the internet connection. There doesn't appear to be anything wrong with chess.com (if everyone on the site was experiencing this the forums would have been full of posts about it by now). It's not the browser (because I also get the problem in Firefox).
The only thing that may affect this (and that I'm aware of) that's changed in the last week on my laptop is the upgrade (or more correctly uninstall/install) of AVG from version 8 to 9. Only problem with that theory is that I still get the issue even if I disable AVG's firewall and webshield. Also, everyone else at work was upgraded at the same time and no-one else has reported similar issues (although none of them frequent chess.com, which appears to be affected much worse than other sites).
The chess.com site seems to be badly affected, but I've seen it happen on other sites too. Most notably Google news and the admin console of my router at home (more proof that the connection to the Internet isn't what's causing the problem). I'm guessing, but I think it might have something to do with sites that use Javascript to refresh pages or portions of pages automatically (something all three these sites do). The only problem with that theory is that I haven't seen the issue at all on gmail or google documents, both sites that also do that and sites that I use frequently every day.
I'm at a bit of a loss as to how to resolve this, but would appreciate it if anyone can help me shed some light.
Thanks
Anton
