Hi guys,
Sorry for not replying on this. I hadn't seen the thread till testcase alerted me to it.
I have to say that, having looked at a couple of your accounts, it would seem that CTR has certainly tanked on those accounts in the last few days. This mixed with a day where traffic seemed to rise on Saturday - mostly on IDN domains, but it would appear on others as well, doesn't really paint a great picture. We are looking into what is causing the lower CTR and the increase on traffic on Saturday - usually not a very high traffic day.
Hopefully this is just a small blip and normal service will be resumed asap...
Sorry for the inconvenience guys, we're doing our best to see what's going on.
Ed
