On Monday, 20 July, 2020 around 12:50pm UTC, Pantheon platform experienced a lack of compute capacity in the European Datacenter causing some servers in the region to be unresponsive. The incident affected 0.5% of customer sites within that region. 

We addressed the capacity issue and worked with our upstream provider for the EU to increase our quota in order to provision additional spare capacity.

The incident was resolved at 5:01pm UTC after affected customer sites were moved to the new servers.

Our Engineering team is taking actions to prevent a situation where capacity is not available without an upstream provider. We are taking a look at the process in which we evaluate our capacity in non-US regions preventing such an incident from happening again.
