MtGox trades frozen?

[nmat]

The last successful trade was half an hour ago and I am not being able to sell. The orders just don't go through. Anyone has the same problem?

Bitcoin Monitor shows some MtGox trades going through, but very infrequently.  Most of the trades in the last 30 minutes were on TradeHill.

It's coming back now... It was like this for almost an hour I think:

Speaking of Mt. Gox and trade frequency...

The site is a bit "dead" today, don't you think? 

Besides the fact that BTC are trading in a 30-cent range for the past 24 hours, volume also seems extremely light.

Can't seem to get orders to go through here either. Put in a sell order well below market just to see if it would go
and it just sits there. LOL, stuck in "real-time".

That a guess or reliable info?

I'd expect a more than one word post from someone labeled staff when it's actually about something legit.

I still can not trade, and my withdrawal to dwolla 10 hours ago is still not processed

Edit: trades do work apparently

[nefanon]

Is this why the average trade has dropped 40 cents?

[nefanon]

Correction, it's dropped over $1.75 now. WTH is going on??

[Sannyasi]

same for me, none of my sell orders that i've placed in the last two hours have went through, most all of the sell orders were under buy price..... oh well

[Mer]

Likewise.  My buy and sell trades should have both executed.

It seems to me a bit difficult to understand how a DDOS would impact an exchanges ability to make trades on their books.  Or even publish their books for that matter.  My guess is that they must be scrambling to rectify balance issues associated with some of the other money problems over the last few days.

I think that it is perfectly appropriate and expected that people will postulate about issues on non-official message boards which are considered unimportant enough by the exchange to not bother participating in.

I just put in a pretty big and very low buy order on another exchange just in case MtGox turns out to be the next big domino in the string of Bitcoin enterprise misfortunes...So if TPTB here wish to move this to speculation, knock yourselves out.

Same problem here.

Reminds me of boxing day. Everyone rushes into buy except for this everyone is trying to sell

Not enough said at all.  A DDOS would typically somewhere between unnoticed and terminal for a gateway machine, but I would not expect that in any but the most primitive of architectures that would have any impact on their back-end machine(s)...except to free the backend machines up from some fraction of trades (from people/bots that could not get in) and allow them to run faster.

Whether they are using MySQL, Reddis, or whatever for their processing engine, I cannot imagine that it is subject to failure of their gateway machine(s).  If so, that's mighty sad.

i don't know their architecture, but am going to speculate that they are possibly doing logging where requests write to the database or something else where auth attempts from a ddos have an impact against the database.

days ago when mtgox was under a different ddos attack, tux said something to the effect of a backup process that runs hourly implements a lock but that process was being impacted as the result of the ddos.  because the backup had locked but wasn't succeeding, then trades were not occurring. 

this may be all be way off the mark but there hasn't been any better info to explain the underlying problem but we now have two ddos attacks that we know of where trading was impacted.   

assigning blame to the use of mysql was wrong, sorry.  the intended point was that this exchange wasn't built with the same technologies or dev team that an etrade or oanda are built with.
