Starting from 2/24/2017 4:00 AM UTC customers who are sending data at a rate faster than 8K eps will experience throttling during data ingestion. This is due to some optimizations that we are making to some of our pipeline services. We do not expect normal data ingestion use cases to be affected by this temporary change in ingestion rates. Only customers ingesting at a rate faster than 8K eps will be throttled.
Our DevOps team is actively working on this and we will update this thread once we are able to scale the ingestion rates back up. We apologize for any inconvenience.
