1  Economy / Service Announcements / [ANN Mt.Gox] Statement Regarding Recent DDoS Attacks and Mitigation on: April 25, 2013, 01:48:44 AM
Dear Mt. Gox Customers, Dear Bitcoin Community

We've prepared a short explanation of recent events related to DDoS, as well as some answers to common questions we've been receiving. You can download the .pdf here:

Thank you, and we look forward to following up on any questions you may have.

Regards,

Mt. Gox Team
2  Economy / Service Announcements / [ANN Mt.Gox] Resuming Operation: Now what? on: April 12, 2013, 03:13:14 AM
https://mtgox.com/press_release_20130412.html

As announced yesterday, (https://mtgox.com/press_release_20130411.html) we have decided last night (https://support.mtgox.com/entries/21519569-Market-Cooldown-for-12-hours) to shutdown all trades for 12hrs.

This decision was made based on two major factors.

1. Trade Engine Lag
We have seen an astonishing growth in both volume and number of people joining Mt.Gox and trading on our platform. While we were ready and expected to see the number of new customers and trade rising, we did not anticipate such AMAZING growth that has been partially translated in visible and unbearable trade engine lag.

To fix this issue, we decided to make some major changes in our hardware infrastructure. It is now capable of handling 50 times more of the trades than in the past, giving us more time to release our new and improved trade engine, which is scheduled to be launched within a month.

2. DDoS
We have seen our fair share of DDoS attack in the past, but the sheer volume of the DDoS we received in the past couple of day was rather important with a peak at 80Gbps. Despite our service provider's best effort, we had a lot of difficulties to handle both our user growth and the DDoS.

What’s next?

Technically speaking, we are now ready to better handle our exchange's rapid growth and assure normal operation. As far as the DDoS are concerned, we are still fine-tuning our security features and actively working on implementing a solution that will drastically protect us from such huge attack in the future.
But rest assured that we are taking this situation very seriously, and that we are doing everything in our power to protect the Exchange and your trade from such attacks.

Even as we speak, we are still being attacked by a yet unknown group of people that have clearly an intention in hurting Mt.Gox and Bitcoin as a whole. But rest assured that we are not giving up and are dedicated to win this, one way or another!

What will happen to all the pending trades?

This has been discussed at length here at Mt.Gox. We have decided that we will not flush the order book before trading resumes. We have no intention in proactively clearing people’s order regardless of what’s happening, and we will let people be the judge of what’s best with their order.
There is no doubt that we are expecting a violent crash of Bitcoin after trading resumes, but we are confident that this Panic Sell will be temporarily and that Bitcoin will rise again.

Also active immediately, we will waive all trading fees for the next 48hrs (Starting from 11am today JST).

Finally

Again, thank you for your continued support. Despite suffering one of the most impressive DDoS that we ever seen, we are doing everything in our power to overcome this situation and to restore stability and confidence in our exchange.

Mt.Gox Co. Ltd Team.

3  Economy / Service Announcements / Re: [ANN Mt.Gox] Hi everyone, just a quick update on the situation and what happened on: April 11, 2013, 04:44:15 AM
I would have more sympathy if this was not part of a long history of lackadaisical malfeasance on the part of MtGox.  You have no incentive to fix your steaming pile of crap and I do not believe you will.

You are obviously no ideas of what you are talking about, come and work with us you will see how things are done and what we have to deal with on a daily basis. As I write this we have two concurrent DDoS attack with NO lags and still online. Things always seems easy at the other end of the keyboard.
4  Economy / Service Announcements / [ANN Mt.Gox] Hi everyone, just a quick update on the situation and what happened on: April 11, 2013, 04:20:37 AM
https://mtgox.com/press_release_20130411.html

First of all we would like to reassure you but no we were not last night victim of a DDoS but instead victim of our own success!

Indeed the rather astonishing amount of new account opened in the last few days added to the existing one plus the number of trade made a huge impact on the overall system that started to lag. As expected in such situation people started to panic, started to sell Bitcoin in mass (Panic Sale) resulting in an increase of trade that ultimately froze the trade engine!

To give you an idea of how impressive things were here are some numbers that we would love to share with you guys:
- The number of trades executed tripled in the last 24hrs.
- The number of new account opened went from 60k for March alone to 75k new account created for the first few days of April! We now have roughly 20,000 new accounts created each day.

Due to these facts we have been busy working on improving things since last week and our team has been working around the clock to improve Mt.Gox to catch up with the demand. We will continue to release several updates today and in the coming few days to improve our system overall performance.

Also please note that we may have to close the exchange for two hours in the next 12 to 24hrs to add several new servers to our system.

Thank you for your understanding and continuous support!

5  Economy / Service Announcements / [ANN Mt.Gox] Orders will only be accepted when there are enough funds available on: April 09, 2013, 05:16:29 AM
https://mtgox.com/press_release_20130409.html

Dear users, starting on April 17th we will be rolling out a minor change on how people place orders via the Mt.Gox interface.

Until recently, anyone could place a buy or sell order for Bitcoin, regardless of how much funds were actually available in their wallet, resulting in an order showing a "Not enough funds" error status in the Open Orders list.

Starting on April 17th, this counter productive scenario will no longer be possible and will be automatically rejected before validating your order; until you have enough funds in your wallet to match the order value.

While this change should only affect a minority of users, it will however have a major impact on our trading platform and improve our system overall performance.

Thanks!

We, Coinlab & Mt.Gox, will announce something on this matter soon.

I really hope so because to date both services have fallen well short of the mark in keeping users informed.

I agree with you, but let's say that the FinCEN announcement delayed a few things.

Prolexic sucks, they are resellers. Go with Black Lotus and make them agree to guaranteed uptime protection they'll do it. You could also clone a backup elastic cloud image on Amazon that ssh's to your secure db and switch to it whenever you get hammered beyond 10Gbps

We were using Black Lotus and runaway from them... And 10Gbps is pretty much nothing for us, we have this on weekly basis and EC2 doesn't have enough CPU/memory to handle our db on a single instance
8  Economy / Service Announcements / Re: [ANN Mt.Gox] It’s been an epic few days: What happened? on: April 04, 2013, 03:52:48 AM
Alex, you mentioned the verification issue.

It's really unclear to me what is going to happen with this when US/Canadian users get transferred to CoinLab.  Will the accounts which are currently awaiting verification still be verified by MtGox or will US/Canadian customers be verified by CoinLab following the transition (ie, will those US/Canadian customers currently awaiting verification by MtGox need to start the verification process again with CoinLab)?  

The lack of recent information about the transition is worrying as customers were initially told that they needed to agree to CoinLab's ToS if they wanted to use MtGox following the transition but the information on the CoinLab site says that the funds of US/Canadian customers will automatically be transferred to the US.  

This implies that people will need to withdraw their funds from MtGox before the transition if they don't want those funds transferred to the US bank (which may present difficulties for unverified customers given the backlog on verification) or they'll have to register as a CoinLab user whether they want to or not in order to withdraw their funds.

It was previously stated that MtGox user data would not be transferred to CoinLab without user agreement (ie, MtGox users accepting CoinLab's ToS), but if the funds are being transferred automatically then how will users be able to access them without using CoinLab?

I know you have a lot going on, but the transition to CoinLab has to the potential to be disastrous if you don't keep your users fully informed and - quite frankly - you don't need any more things happening right now which undermine people's confidence in you.


We, Coinlab & Mt.Gox, will announce something on this matter soon.

Dear Mt.Gox users and Bitcoiners,

It’s been an epic few days on Bitcoin, with prices going up as high as $142 per BTC. We all hope that this is just the beginning!


Thought the top was $147?

You are right (last 24hrs), I was stuck on the past 12hrs data
10  Economy / Service Announcements / [ANN Mt.Gox] It’s been an epic few days: What happened? on: April 04, 2013, 02:52:05 AM
Dear Mt.Gox users and Bitcoiners,

It’s been an epic few days on Bitcoin, with prices going up as high as $142 per BTC. We all hope that this is just the beginning!

However, there are many who will try to take advantage of the system. The past few days were a reminder of this sad truth.

Mt.Gox has been suffering from its worst trading lag ever, 502 errors, and at one point some users were not able to log in their account. The culprit is a major DDoS attack against Mt.Gox.

Since yesterday, we are continuing to experience a DDoS attack like we have never seen. While we are being protected by companies like Prolexic, the sheer volume of this DDoS left us scrambling to fine-tune the system every few hours to make sure that things don’t go beyond a few 502 error pages and trading lag.

Why has Mt.Gox become the target of a DDoS attack?
It is not yet clear who is behind this DDoS and we may never know, but these actions seem to have two major purposes:

1.   Destabilize Bitcoin in general.
It is not a secret Mt.Gox is the largest Bitcoin exchange with more than 80% of all USD trades and more than 70% of all currencies. Mt.Gox is an easy target for anyone that wants to hurt Bitcoin in general.

2.   Abuse the system for profit.
Attackers wait until the price of Bitcoins reaches a certain value, sell, destabilize the exchange, wait for everybody to panic-sell their Bitcoins, wait for the price to drop to a certain amount, then stop the attack and start buying as much as they can. Repeat this two or three times like we saw over the past few days and they profit.

What can be done?
Believe it or not, there is pretty much nothing that can be done. Large companies are frequently victims of these kinds of attacks. Even though we are using one of the best companies to help us fight against these DDoS attacks, we are still being affected.

There are a few things that we can implement to help fight the attacks, such as disconnecting the trade engine backend from the Internet. By separating the data center from the Mt.Gox website, we will continue to be able to trade.

What can you do?
Like our favorite author here at Tibanne says… Don’t Panic!

“Panic-selling is a wide-scale selling of an investment which causes a sharp decline in prices. Specifically, an investor wants to get out of an investment with little regard of the price obtained. The selling activity is problematic because the investor is selling in reaction to emotion and fear, rather than evaluating the fundamentals.” (Source: Wikipedia)

I understand that many of you have a lot at stake here, but remember that Bitcoin, despite being designed to have its value increase over time, will always be the victim of people trying to abuse the system, or even the value of Bitcoin decreasing occasionally. These are not new phenomena and have been present since the beginning of time when humans first started trading.

Trade Engine Lags
Lag affects everyone, not only us, but also major, world-renowned exchanges like the NASDAQ and NYSE. We can fix lag, but we cannot eradicate lag. Only small exchanges with low volume and liquidity are immune to lag.

Does this mean that we are giving up fighting lag? Hell, no. We are working on it by creating a new trade engine that will solve many problems, but it’s not a magic bullet. We can always try to scale our servers, but we cannot predict what happens from external sources: DDoS, panic selling, immediate increase of buyers, etc. Lag will always be there, but our mission is to make lag as small as possible.

Account Verification
As if a major DDoS attack was not enough, we at Mt.Gox are victim of our own success!

Last year, Mt.Gox saw an average of 9,000 to 10,000 new accounts created every month. This number doubled in January, tripled in February, and sextupled in March. In this month alone, March, over 57,000 new accounts were created!

Our support and account verification team went from four people in January 2012 to twenty-two people working every day of the week. We are now hiring even more people to solve this problem by finalizing some deals with external companies.

Remember that even if you are waiting for your account to be verified, you can still deposit or withdraw funds via our Japanese account and make your trades! (Only accounts that we pro-actively required to be verified are limited to deposits and trade only.)

Finally
We have seen a significant amount of comments on the web (various forums, Reddit, etc.) that portray Mt.Gox as a company held by “idiots” and other rather rude words, complaining about inability to deal with lag and other system issues, without understanding the magnitude of work and attacks we are facing every day.

I understand the frustration many of you feel. We hate this situation as well. Since we took over Mt.Gox, we have been through Hell and back and we are still here. We are still the largest exchange with over 420,000 trades per month and  USD $121 million monthly trade volume. We have worked our way through all the requirements needed to run our exchange legally.

Now, there are some things we can improve, but so far we are doing an incredible job that no other exchange has been able to do so far. While I understand a certain amount of frustration, realize what we have accomplished. I appreciate all the work you are doing everyday to push things forward and to help secure the future of Bitcoin

And to all of you who are supporting us on a daily basis, thank you! We could not have done any of this without your help!

12  Economy / Service Announcements / [ANN] Mt.Gox announces new withdrawal limit rules for its customers on: March 13, 2013, 09:12:45 AM
Due to recent events in the Bitcoin community and the spike in the Bitcoin price we at Mt.Gox are putting in place a new daily withdrawal limits.

While our daily limits for traditional currencies will remain unchanged with a maximum of $1,000 USD per 24 hrs, the Bitcoin daily withdrawal limit will change from 200BTC to 100BTC per 24 hrs for unverified customers.

Verified and Trusted customers that already have their daily/monthly limit raised will not be affected with this change, however, Verified and Trusted customers that hare not yet asked for their withdrawal limit to be raised will then be offered the following limits :

Verified Status (Level 1)
Maximum monthly withdrawal of 50,000 USD (or equivalent) capped to a maximum of 10,000 USD per 24 hrs and a 1,000 BTC withdrawal per 24 hrs without any monthly limit.

Trusted Status (Level 2)
Maximum monthly withdrawal of 500,000 USD (or equivalent) capped to a maximum of 100,000 USD per 24 hrs and a 10,000 BTC withdrawal per 24hrs without any monthly limit.

Of course we will re-evaluate these limits and adapt and revert them to their past value if necessary and if the value of Bitcoin against USD decreases.

16  Economy / Service Announcements / [ANN] Mt.Gox announces its new multi-platform mobile website on: March 06, 2013, 04:37:18 AM

Handing over 80% of the bitcoin users details certainly makes network analysis a whole lot easier. When combined with access to the bitcoin foundation database thats a massive data goldmine.
You're over-estimating the number of US customers, or under-estimating the rest of the world.


I concur! While everything "started" there things are moving fast, very fast pretty much everywhere!

A medical insurance bill?
What about an auto insurance bill?

If less than 3 month it should be fine.

"We're excited by, and awed at the responsibility we have caring for our over 100,000 new customers..."

I need to get my head wrapped around this. This implies that Mt. Gox may have over a quarter of million unique customers, 100K of which (all unique) are US and Canadians. This blows my mind.

It truly reads 100K new customers and not 100K new accounts, for there is a big difference between the two statements. Remember the email dump? That consists of over 60K accounts, many, many, many of which were multiply accounts by the same users.

If memory serves me correctly, MtGox ToS limits you to one personal and one business account per customer without prior approval.  I suspect that there are a lot of inactive accounts in among that 100,000.  I suspect that many people ignore that provision, too.

The email dump was a long time ago.  I have no problem imagining that the number of MtGox accounts has increased dramatically since then.

It is true that out TOS limits you to one personal account... There is indeed some inactive accounts but fortunately for us not so many. And as for today we have 311850 customers (over 100k in the US)
