We've finally got some money coming in, so we can migrate to a larger server setup. More info on the front page. HURRAY. (I promise you - none of you are as p***** off about the database errors as I have been.)

Yeah, some people seem to forget you, the admins and moderators are suffering, too. Looking forward to a smoother experience.

I suspect your traffic will grow exponentially for a year or two and every couple months or so there will be a mad scramble for increased capacity. If affordable Amazon EC2 would be ideal as you can add capacity as needed. Alternately this may be a perfect opportunity to experiment with an elephant in a bramble: a hadoop map/reduce cluster! Map tasks run on individual 'Pis in the cluster, Reduce task(s) on the master node, which can be a hefty x86 server. Pi->Pi comm. will be much less than Pi<->master node so this should be a fairly scalable solution. 100 'Pis will give you 400MB/s to 1GB/s peak flash disk bandwidth, 10Gbps Pis<->master node bandwidth, 140,000 bogoMIPS processing BW (more, if GPUs can be deployed) etc. Probably $5K to $6K H/W cost, $500/year electricity + Internet pipe cost + management costs. Hm... not ideal and it will take a few months but 'Eating your own dog food' is also the best way to shake out bugs!

I was starting to think that the forum was running on a pi cluster :-p

Of course you say no more DB errors, but the day will come when Stephen Fry will unleash his Twitter Army upon you—it"s only a matter of time.

Speaking of which, I note he gave some Twitter loving to CoderDojo yesterday; nice to see him "bigging up" the whole kids + programming malarkey: https://twitter.com/#!/stephenfry/statu ... 7274733571

I think you should look at fixing the software before / in addition to throwing hardware at the problem.

Are the shiny new servers fitted with go faster stripes as well?

No, but you hide it pretty well (most of the time, anyway!)
