Update - It has been a moment since we updated you. AWS status is still "degraded" (https://health.aws.amazon.com/health/status), so we are going to keep this status posted, just in case.

Monitoring - If you haven't heard, AWS has been experiencing partial outages all day. A huge chunk of the internet uses AWS, and some of Letterhead's features do too: mainly integrations. Our dashboard metrics may appear a bit laggy, or if you rely on in-app tutorial tooltips, you might find that those fail to render consistently. Our support chat may also be affected. Letterhead's core services, however, are not on AWS - so we don't expect significant impact.

All that said, we are monitoring the upstream situation, and we will let you know if it impacts you.

Resolved - This incident has been resolved.
Oct 20, 09:52 EDT
Monitoring - We identified the underlying issue in the delay and have ensured that any delayed automation has now processed. However, you may have experienced having a preview email arriving slower than normal, or a delay in actually sending a recurring newsletter. These have been resolved, but we'll continue to monitor.
Oct 20, 08:34 EDT
Identified - This morning we are noticing that some automated recurring newsletters are delayed in their processing. We are currently looking into the delay.

Resolved - This incident has been resolved.
Oct 8, 11:44 EDT
Monitoring - It looks like our patch addressed issues for older newsletter editions, but we will monitor for a moment.
Oct 8, 11:10 EDT
Identified - We have identified the issue as it affects newsletters that were made before we introduced advanced styles. Ostensibly, this is a regression we introduced, and we didn't test for those earliest templates created. We have just deployed a patch and will observe for a moment before we change status.
Oct 8, 10:33 EDT
Investigating - There is presently an issue when cloning a past newsletter edition wherein certain blocks from that edition aren't showing in the new version. Because they're missing, you can't edit them - but they'll still render in preview. We're currently working on it and will keep you posted.
