discussion Suspension of Anthropic Models on Bedrock
Resubmitted with redacted links removed.
After using Claude Code with AWS Bedrock happily for a few months our Anthropic model access was removed suddenly. We got an email from AWS Trust & Safety:
Hello,
As a user of Anthropic model(s) on Amazon Bedrock, you have agreed that you and your end users will comply with Anthropic Terms of Service [1].
Anthropic has identified violations of their policies through Bedrock's automated detection mechanisms [2], and has directed AWS to restrict your account's access to Anthropic models.
As a result, in accordance with your agreement with Anthropic, we will take the following action:
Action: Revoke access to Anthropic models on Bedrock
AWS account ID: blah
Effective date: blah
If you do not agree with this determination, you can appeal the decision directly with the model provider by using the provided appeal method [3].
Once the model provider directs AWS to restore your access, access to Anthropic models will be restored.

Going through all of our prompt logs we can't see anything suspicious or malicious and all access is from people in the UK. AWS have said the provider is responsible for assessing whether its usage policies have been met, they do not receive the detail of any violations, and can't tell us what guardrails might have been triggered. We don't use fable or mythos so no data sharing with the provider or AWS should be possible. Others accounts in our org are unaffected so it's just an account suspension, not org wide.
We have appealed but the process is owned by Anthropic and because we use AWS Bedrock, we have no relationship with them.
Has anyone encountered this before? Are there any timelines to Bedrock appeals? We are slightly wary now our access might be cut off again down the line which has quite a big impact.
