We intend to remove the silence on DatasourceNoData alerts the week of 2024-1-22. Please amend or remove the alerts beforehand to avoid receiving these alerts.

DatasourceNoData alerts are fired when no data has been received for the configured time window. This could be caused by an alert left behind after the data source stopped producing metrics or some other alert misconfiguration.
From graphite-synthetic-testing, there are two alerts currently in this state:

• Increased first visual change when searching on Obama from the portal start page
• Increased first visual change when searching on Obama at Google coming to Wikipedia on emulated mobile
