We are experiencing intermittent failures in outbound email delivery, including two-step verification codes for sign-in. The cause has been identified as a degradation at our upstream email delivery provider, which is intermittently rejecting messages. Impact: some users may not receive their verification code on the first sign-in attempt, and some notification emails may be delayed. No customer data is affected and no other functionality is impacted. We are monitoring the provider's recovery and will post updates here as the situation changes.

Our upstream email delivery provider has resolved their performance issue and subsequently we can consider this issue resolved.
