Both recent GCP outages caused by fiber optic maintenance

Both of GCP's recent outages were caused by "fiber optic maintenance". On August 20th when us-west1 went down they said [1]:

> The disruption originated during scheduled fiber optic maintenance, which unexpectedly compromised network capacity between data centers within the us-west1 region.

Then on September 1st when us-central1-b (and collateral affects in other zones) went down they said [2]:

> The immediate technical trigger for this event was the inadvertent physical disconnection of network fiber-optic cables during a routine hardware maintenance procedure.

Not sure if they're related but apparently procedures we're significantly changed after the first incident to prevent the second incident.
