We're very sorry if you suffered from the periods of slow responses and elevated error rates with Capsule yesterday. We’ve tracked the issue down the a bug in our data stores query optimiser that resulted in what should have been a fast responding query taking several minutes to complete. This only happens in rare situations with an unusual configuration of data.

While we fully understand the exact nature of the optimiser bug we have applied a fix that stops the bug from occurring. Once again we’re sorry for this disruption this caused.
