Thanks Amy for keeping us informed.

Glad that the issue has been fixed. As Brett suggested, we should briefly
discuss this in the next CSC meeting.
Just a quick question. Did the engineer manually changed the system setting
or changed some automation/deployment scripts incorrectly which caused the
issue ? May be worth hardening the process here for robust deployment.

> Dear CSC,
> We would like to inform you of a system issue that degraded our service
> performance recently. This issue will impact SLA performance for May, and
> is expected to have an impact on our performance in June.
> On 20 May 2022, during a planned upgrade to the Root Zone Management
> Systems (RZMS), an engineer managing the release mistakenly altered a
> system system setting that caused automatically generated emails from the
> system to not be delivered to external parties. These emails included
> prompts for TLD contacts to authorize change requests, and notifications of
> system events such as technical check remedy and completion. Additionally,
> users were unable to receive links via email to reset their passwords.
> The issue was not caught through our SLA monitoring as emails were being
> sent successfully from the system, but not being routed correctly once they
> had left RZMS. Customers first reporting issues on 27 May 2022, and the
> issue was identified and resolved on 31 May 2022.
> We’ve identified that six TLD change requests and five users attempting to
> reset their password were impacted. While the issue did not trigger any
> deviating from the SLAs as they are measured, we believe it would be
> consistent with the intent of the SLAs for these to show these instances as
> breaching the SLAs. For this reason, we have proactively adjusted the
> timings for the SLAs in these cases where possible.
> IANA is working with ICANN’s Engineering and IT Department on adding
> additional safeguards on future upgrades to prevent this issue from
> recurring.
> We are happy to answer any questions you may have, either on the list or
> at our meeting next week.
