Hi Sparrow,
Yes, very sorry about that.
It seems our database server downtime was due to an accident on the part of an employee at the company that hosts our servers. This prevented the database from fetching the proper path for the banners. Our servers are hosted with a major provider who serves many of the biggest organizations in the industry, but these things happen. It took a little while to track down the problem because it was such a freak occurrence.
The good news is that to ensure that banners are still served during unexpected database server downtime, we have put a redundant system in place that will allow the webserver to serve the proper banners independent of the database. All clicks and impressions were recorded during this time and were imported once the database server was restored.
Everything should be running smooth as usual now.
Thanks.
Daniel
