This morning we experienced hardware failure on one of our primary database servers. This led to degraded service for Topsy, the Otter API, and the Topsy Retweet Button for approximately 10 minutes this morning around 10:45am PST. At this time, we've recovered, and all services should be functioning normally, although hourly results will be lagged for a few minutes as we recover from the backlog created by the hardware failure.
