I have a feature request. Could you please be slightly more verbose about all the charts? Could you please add a chart that shows the count of addresses that actually hold coins?

I will add this chart and the one suggested previously at the weekend.

Hey piuk, I assume the above didn't make it into your busy schedule for the past weekend but would you perhaps have a new ETA for it? Just curious..

Hi,

I noticed that I no longer get a profit/loss result for satoshidice on blockchain.info - is there a limit to the number of bets or addresses for this functionality to be enabled - I found it quite useful

Is this something you would consider? Blockchain info for testnet and the API to test on? It would be a little nicer from a development standpoint to test applications with play money before real BTC start flying around in beta code.

Possibly, It would need to be run on a separate database/server but I could certainly see it being useful.

Were there any changes made to the logic of transactions with many small outputs? I'm having trouble with "Insufficient funds" error message again, now the balance of the first output from the drop-down list is quoted as available to send. It was Ok till late evening of 2/9/12 both in FireFox 13 and Chrome 24.0.1312.56.

Thank you in advance for looking into this issue!

I haven't made any changes since then. May I ask the bitcoin address again?

Have you imposed a hard limit of 100 outputs per transaction by any chance? Is there any way to relax it to, let us say, 200? I think there was a hard limit of 250 some time ago, but it was dropped afterwards, if I'm not mistaken?

Yes this is correct. The limit was reduced to 100 as some users where reporting problems with very large transactions not confirming and incurring unexpectedly high fees. I've adjusted the limit to 200 now, this should be enough for the vast majority of transactions.

Do you provide API support for test net?

No not currently.

The migration of the final Innodb tables to Cassandra is now complete. A MySQL crash will no longer be enough to bring the site down and I am confident there will be no more downtime anytime soon. The Site is now running 4 Ndb nodes, 3 Bitcoind instances, 2 Cassandra nodes, 2 MySQL nodes and 2 Tomcat instances.

Awesome to hear!

Thank you, added.

This is missing in the Chrome app.

It will be getting an update in a day or two with some other changes. As the javascript cannot be changed remotely it can lag behind a bit.

It would be better if you could tag your coinbase transactions though.

For me, the send transaction button disappeared before I could press it, and it did not go through. Attempted three times.

I can log in to my account now, but can't send a transaction. Some error about a bad script.

I got the same error, but the transactions went fine.
I was about to hit the send button twice, but I stopped to think for a second and saw the transaction in the history.
I was 1 click away to screw everything up.

not sure if I'm reading this thread right but did it take you 6h to get aware of your >1,000,000Ƀ/month processing site being down?

Unfortunately yes, everybody has to sleep sometime.

Quote from: giszmo on February 06, 2013, 07:37:14 AM

Do you use some monitoring like zabbix? You or one of your technicians should get an SMS within a minute or five and not rely on somebody eventually looking at the forum.

The site is monitored by Pingdom and I do get SMS alerts. But other than the datacenter operators who can perform restarts there is no other technician with access to the server roots. I am looking at bringing someone on full time but the issue is finding a good candidate whom I trust. In the short term a fallback to electrum will help.

I am extremely sorry for the downtime everyone. It was an issue with the database SQL server (not the database itself) not a security issue.

The site still relies on one MySQL server for some database lookups (the actual backend is ndb with data split across 4 servers but all sql queries still route through one mysqld instance) unfortunately when this crashes it brings the site down with it. In order to provide tolerance of this event happening again load balancing between two mysqld instances is needed but there is one innodb table that is preventing this switch currently. My top priority is now to get the innodb table migrated across to cassandra and get two or more instances of mysqld running.

Hi Piuk,

not sure if I'm reading this thread right but did it take you 6h to get aware of your >1,000,000Ƀ/month processing site being down? Naively that would calculate to 8,000Ƀ being sent later than planned which can be super annoying when you meet for a trade in the street. (Maybe MyWallet was not affected but the response time might be the same.)
