Storefront: Email Delivery Issue for Yahoo & AOL Addresses

Incident Report for Tillo

Resolved

We are pleased to confirm that the content filtering issue has now been fully resolved.

All propagation periods have completed, and major providers—including Virgin Broadband and Yahoo Mail—alongside smaller networks, have successfully updated their systems.

Current Status:

Full Access Restored: Gift cards are now accessible across all internet service providers (ISPs), mobile networks, and Wi-Fi connections.

Workarounds No Longer Needed: Users no longer need to switch to mobile data to access their gift cards.

We appreciate your patience and cooperation while we worked with external providers to clear this restriction. Our teams will continue to monitor our systems to ensure ongoing stability.

Monitoring

We are pleased to report that the recent content filtering issue is now largely resolved, with only minor, isolated disruption remaining.

Current Status:

Major Providers Resolved: Whitelisting has been successfully processed by major providers, including Virgin Broadband and Yahoo Mail, as well as the various companies and services operating on their infrastructure.

Tailing Issues: Users on these major networks should now have full, uninterrupted access. We are currently tracking a few remaining tailing issues with smaller, niche internet service providers (ISPs) as their local systems finish updating.

What to do if you are still affected:
While we wait for the final smaller providers to catch up, the previously shared workarounds remain effective:

Immediate Fix: If you or your customers are still experiencing blockages on a local Wi-Fi connection, temporarily switching to a mobile data connection will bypass the restriction and allow immediate access to gift cards.

Re-send to non-impacted domains via the Storefront hub.

We are continuing to monitor the situation closely until all remaining minor disruptions are fully cleared. Thank you for your continued patience.

Investigating

We are currently experiencing an issue where emails are not being delivered to Yahoo and AOL email addresses for StoreFront orders. Our team is actively investigating the root cause and working to restore full email delivery as quickly as possible.

This issue affects Storefront customer orders who have a Yahoo email address (e.g. addresses ending in @yahoo.com, @yahoo.co.uk, @Aol etc.). Users with other email providers (Gmail, Outlook, etc.) are not affected.
