Is Exclaimer down?

We’ve identified an issue affecting directory synchronisation for customers in the EU region. Synchronisation is temporarily paused while our engineers resolve it. User data that was already synced shouldn’t be affected, but changes to user data and newly added users won’t sync until it resumes, and the Synchronise button in the portal may stay on “In progress”. Customers setting up Exclaimer for the first time will also be affected, because their initial user sync won’t complete until then. We’re aiming to restart synchronisation tonight, and we expect data to be up to date by the morning of 27 October. This is our current estimate, and we’ll post an update as soon as syncing has resumed.

Exclaimer Engineers are continuing work to address the impacted service. Please note that any user data previously synchronized with Exclaimer will remain unaffected. However, any updates to user information or the addition of new users will not be reflected in signatures until the issue is resolved.

Exclaimer Engineers have been able to address the issue preventing Data synchronisations from running, and we have now enabled manual synchronisation again. Users who see an 'In Progress' status on the Sender Management page within the portal will be able to start a new Sync using the 'Start Sync' option to allow Exclaimer to obtain the latest user data. If you are continuing to experience issues, or see an error message appear, please contact our support team who will be happy to help.

Auto synchronisation has been restored and is expected to run according to its configured schedule. We are continuing to monitor subsequent synchronisation runs to ensure its functioning as expected

Engineers have confirmed that the previous service alert has been resolved. The service is now back to full health and is working as normal. Thank you for your patience.

Exclaimer Engineers are aware of a possible issue that is preventing some subscriptions from accessing the Exclaimer Portal. The cause is currently being investigated, and more information will be shared shortly.

Exclaimer Engineers are taking action to restore the service to full operation at this time. We have been able to confirm that signatures being applied through Client-side and Server-side methods are continuing to apply as expected.

We've restored access to the Exclaimer admin portal and management pages for the UAE region by redirecting traffic to our secondary UAE infrastructure. Our checks show the pages loading normally again. We're continuing to monitor while we investigate the underlying cause. Email signature delivery wasn't affected. We'll post another update when we have more information.

The cause of the issue has been identified, and mitigation has been applied to restore full access to the User Interface for impacted customers.

Exclaimer Engineers have confirmed that the incident has been resolved. The issue was caused by a Cloudflare incident (https://www.cloudflarestatus.com/incidents/ryvhi2suec0d) affecting connectivity between Cloudflare and Azure that prevented routing traffic to one of our available UAE Datacenters, which remained healthy throughout. Exclaimer Engineers worked around the issue by routing traffic away from the impacted route until Cloudflare had resolved the issue and all traffic is now routing as normal following testing and a period of extended monitoring. If you have any questions or concerns, please reach out to our great support team, who will be more than happy to help answer any questions.

Exclaimer engineers are investigating a delivery delay affecting some messages sent from Outlook and Exchange to Exclaimer Cloud. Some of these messages may be retried by the sender and may appear as temporary deferrals rather than delivery failures. We are not currently aware of any confirmed message loss and will provide updates as we learn more.

Exclaimer has identified that a small subset of messages (~0.02%) are delayed when routed through Exclaimer due to a suspected issue within Microsoft's servers. This has been raised with Microsoft to investigate alongside Exclaimer Engineers. Sent messages will be received with a signature applied, as expected. If you are seeing issues with message deliverability, please reach out to our support team, who will be happy to assist.

Mail delivery has resumed as normal and our engineers are seeing significantly less errors. The team are awaiting confirmation of a fix implemented on Microsoft servers and will be monitoring until tomorrow morning to confirm.

The original impact of the issue has been mitigated by Microsoft changes. Exclaimer Engineers are continuing to work together with Microsoft to establish a root cause. If you have any questions or concerns, please reach out to our great support team, who will be more than happy to help answer any questions.

Exclaimer engineers are investigating a delivery delay affecting some messages sent from Gmail/Google Workspace to Exclaimer Cloud. Some of these messages may be retried by the sender and may appear as temporary deferrals rather than delivery failures. We are not currently aware of any confirmed message loss and will provide updates as we learn more.

We are continuing to investigate this issue.

Our engineers have confirmed this issue was caused by a change on Google's side, that we have implemented a code change to mitigate and will continue to work with Google to address the issue.

This incident has been resolved.

Engineers have applied a mitigation for the issue affecting mail processing that began at 14:37 UTC. Some messages experienced delays while imprinting was retried, and a small number of messages may have been sent without a signature applied. Our engineering team is continuing to monitor performance to confirm full recovery.

Email signature delivery is operating normally in the US again after mitigation by engineers. Between 14:20 and 14:54 UTC, customers may have experienced some minor delays whilst imprinting was retried internally and a small number of messages may have been delivered without a signature applied. We apologise for any disruption caused.
