March 30, 2008PlayChess ServerThis is our completely new playchess server. It has much more power than the old one. The old server had come to age. It couldn't handle that many games any longer. Some "expensive" features (namely the variant explorer) were too much for it.
I have to apologize for all the trouble in the past. We should have moved earlier to a new server. I hoped that the old server would do its work long enough so that I could prepare the necessary move. But fate has decided differently, so I had to transfer PlayChess to the new hardware in a hurry. I tried my best to check if everything is okay. But PlayChess is a very complex web application. I cannot exclude that I missed something. The games will continue tomorrow (Monday, March 31st, approx. 12:00 GMT).

February 05, 2007Take backI corrected all games, where unintended moves had been made due to the programming error from January 27th. If you still have one of these games, please notify me using the "Problem with..." link on the corresponding game page. Please tell me which move should be taken back (e.g. "18.Nh5Q"). If you see one of your games taken back to a previous position, then probably your opponent had requested such a take back. This was granted, because it has been *my* fault, not your opponent's. I will resume the correction of our older "missing games" problem tomorrow.

January 28, 2007Correction of unintended movesIf you made some moves during yesterday's site update, the system might have stored your move in more than one game. Even impossible moves (e.g. Nf5Q) might be stored into the database. If you detect such an error (only then), please do the following: - do not make any more moves in this game - notify me about this game, please provide the following I will restore the position before that unintended move during the following days (depending on how many problem moves exist). Please apologize all this trouble!

Programming error correctedDespite my extensive testing there had been a substantial programming error. Quite often your entries from previous pages were repeated on the current page - resulting in strange error messages or behaviours. This error is corrected now. You can now make your moves as usual - even move previews, and conditionals should be possible again. Possibly, this error lead to "follow-up problems", which will be repaired as soon as possible. Please report any problems in the forum "Error reports" or send me an email.

January 27, 2007Preview errorThere seems to be a problem with the "preview move" feature. Please do NOT use the previewing of moves until further notice. I will notify you here as soon as the problem is resolved.

September 27, 2006New tournaments availableI corrected the state of several tournaments and created new ones. The missing games problem will probably be corrected tomorrow. Please make your moves in these "missing games" tournaments. The missing games will be created soon.

September 21, 2006Tournament problems solvedI found and corrected the error that caused the tournament problems. You can enroll in tournaments again - if you can find an open tournament. Several tournaments have missing games. In most classes there are too few open tournaments. I will try to correct both problems tonight. Tomorrow most of these problems should be gone. Sorry!

September 11, 2006Server problems solved - for nowToday the server had been down for several hours. The administrators finally got it running again. But I still don't know what went wrong or how they repaired it. Hopefully, the server will be stable for the rest of its lifetime. Yes, we will get a new server. But I cannot say when (as quickly as possible). Until then, let me remind you that the clock buffer (the time you get on your clock when the game is started) is meant to compensate server problems like that. Never, never let you clock drop below 1-2 days! Else, the next server crash might lead to losing games on time. Blogs

June 28, 2005No cookies? No problem!If you had cookies deactivated in your browser, you could run into problems when you tried to open popup windows (e.g. private notes). The server "forgot" who you are. Thanks, Randy (AntoniusBloch), for the error report!

September 04, 2004Inverted boardsSome players saw inverted boards (with themselves on the top side). Background: This problem showed up, if you had set the board orientation (on your preferences page) to "Moving player". Since the program for displaying the chess board used the color of the moving player of the previous game (instead of the current game) the orientation had been calculated wrongly. Acknowledgements: Several players reported this error - thank you all. Especially the detailed analysis of Patrick McCartney made localizing this bug very easy.

Wrong game errorI finally found that strange error. Now again you can see any game played at PlayChess. Thanks for all your hints, they helped a lot. The other problems will be attacked tomorrow (I go to sleep now). I am quite optimistic that I can resolve most of them quickly.

September 02, 2004Strange errorsWe still have some strange behaviour: These errors will be corrected as soon as possible. I already checked the database: your data are okay, don't worry, "only" the display of the games does not work.
