Reporting Exception: An internal error has occurred.

As of this morning, we are receiving a blanket exception on all of our reporting requests to the API. Our system has not changed, and I've noticed that this coincides with your Sandbox downtime, although we are hitting the production API. As a reference, here's the request we made: POST https://adcenterapi.microsoft.com/Api/Advertiser/v7/Reporting/ReportingService.svc HTTP/1.1 Content-Type: text/xml; charset=utf-8 VsDebuggerCausalityData: uIDPo937fvEotBFNpuDL3Zv787sAAAAAmtIz2+NweEuMfRWSWwcsRH7n3YiGn5tOlV2x55XdgyEACQAA SOAPAction: "SubmitGenerateReport" Host: adcenterapi.microsoft.com Content-Length: 2466 Expect: 100-continue Accept-Encoding: gzip, deflate Connection: Keep-Alive XXXXXXXXXCsvEnglishtrueDailyAccountIdCampaignIdAdGroupIdKeywordIdAdIdMatchTypeTimePeriodImpressionsClicksConversionsSpendAveragePosition426608282011372011 And the resulting Exception: HTTP/1.1 500 Internal Server Error Content-Type: text/xml; charset=utf-8 Server: Microsoft-IIS/7.5 X-Powered-By: ASP.NET Date: Wed, 03 Aug 2011 15:35:29 GMT Content-Length: 693 s:ClientInternal system error.
