"Parler is unable or unwilling to promptly identify and remove this content, which is a violation of our terms of service. We made our concerns known to Parler over a number of weeks and during that time we saw a significant increase in this type of dangerous content, not a decrease, which led to our suspension of their services Sunday evening" - AWS Sounds like it was "A number of weeks" so probs 30 days notice.
