We had a network outage last night, which resulted in temporary loss of the data store that keep trackbacks and tweet counts. We are currently rebuilding this store and it will be available within 8 hours. While we rebuild our store, tweet counts will show as 0 and trackbacks will be missing from Topsy.com & Otter. Search and modules are not impacted. 

We apologize for the inconvenience.  We always run two copies of our data stores, but we were operating on a single copy due to our data center move.  We'll be back up soon with redundancy. 

No data is lost.  All counts will be restored when the data store comes back up.
