For about a minute around 10:23 UTC, our servers in one of our two Paris datacenters could not reach any outside network including the other datacenter.
The impact on applications deployed on more than one scaler should be null (apart from database access depending on your particular case). Applications deployed on a single instance had about a 50% chance of being affected.
This network incident had an impact on Metrics, the service was unavailable for 15 minutes after the incident and ingestion has been delayed for another 15 minutes.
As of now, we don't know exactly what happened but we expect that a router malfunctioned and went haywire for a minute.
