Seesaw の障害履歴

There will be a short downtime for the Seesaw Image Library Friday May 8th, 2026

Update is complete, Image Library is now available.

We are currently experiencing issues resolving some images in our Seesaw app. We suspect this might be resulting from stability issues with our underlying cloud service provider (AWS), but continuing to investigate the root cause.

We can confirm that the underlying issue is with our cloud service provider (AWS) and they are currently working on a full resolution.

The incident has been resolved. Our cloud service provider (AWS) has remediated the issue, and all images are now functioning as expected.

We are currently experiencing delays in the delivery of scheduled messages. Our team has identified the cause of this issue and working to resolve it. Scheduled items may arrive later than expected.

This incident is now resolved. Customers will receive all messages that were scheduled during our downtime.

We are currently investigating errors uploading to student journals and activities.

The issue has been identified and a fix is being implemented.

This issue has been resolved. For students who continue to see a "No Internet Connection" error, they will need to force quit the app and reopen it, or refresh their browser page to continue working. Autosave will attempt to recover their work from before the upload issue began after they relaunch the app or refresh the page.

Some third-party authentication services, including Clever and ClassLink, are currently experiencing disruptions due to an AWS outage. This may impact your ability to log in using these services. Seesaw is actively monitoring the situation. Please note, this is not a bug in Seesaw. We will provide updates as more information becomes available.

This incident has been resolved.

We’ve identified an increase in crashes when opening the app from a push notification on iOS version 10.89. Entering the app from the Home Screen works normally. Our team is actively investigating and working on a fix.

A fix has been identified, and a new version of the app has been submitted to the iOS App Store for review.

The fix has been released in the new version 10.89.1 of the app. We have been able to confirm that opening the app from a push notification no longer crashes the app. The team is monitoring the fix to ensure it continues to work as intended.

Following continuous monitoring, the team confirms that this issue is resolved.

We've identified an issue with getting a QR code for a student post from the [...] menu on student work. A fix has been identified and is in progress. Student login QR codes are unaffected.

This issue has been resolved.

A regular maintenance operation to remove old/stale data impacted image fetch abilities within the Seesaw app. While app functionality was not impacted, some images might not have loaded in the app for about ~30mins.

We discovered a ClassLink-side API connection issue. This prevents the nightly sync from completing for some ClassLink districts. We are in active communication with the ClassLink Team who is investigating the issue.

We had an issue where families could not attach files in Messages. This issue is now resolved on Web as well as the latest iOS and Android releases (requires updating to the latest release 10.64.0).

We are currently investigating an issue where class creations via CSV are not working.

This issue has been resolved.

The engineering team is investigating reports that photos from the camera roll are not displaying in Creative Tools. The root cause has been identified, and a fix is in progress.

We have submitted a fix for our iOS app, currently pending Apple approval. In the meantime, we have identified workarounds for the camera roll issue and communicated them to customers who reached out.

This issue has been resolved with our latest iOS App Release (10.51.1).

We are currently investigating some reports of posts and messages that are missing for users in the UK. We will update as soon as we have more information.

We have a temporary mitigation in place for the issue impacting the UK so that Seesaw is now displaying posts and messages correctly for UK users. Users previously impacted by missing posts and messages should be able to see their posts in their Journal (note: some posts may be pending approval in Notifications) and messages will be showing up in the Inbox — no posts or messages data is lost. We are continuing to investigate the root cause and additional improvements and will continue to update with more information.

We have confirmed that with the mitigation in place, all posts and messages are now displaying correctly for UK users — all data is safe and no posts or messages data is lost. (Note: Some posts may be pending approval in the Notifications tab.) We have identified the root cause of the issue as maintenance operations by our cloud service provider and are working with them on a permanent solution.

UK user-facing issue is resolved: All posts and messages are displaying correctly for UK users (Note: Some posts may be pending approval in the Notifications tab). Team has a mitigation in place and is working with our cloud service provider on a path forward.

A small group of our customers in the UK region experienced slowness while loading Seesaw today. The root cause was mitigated, and the engineering team is continuing to assess and fix the root cause. The issue lasted approximately 45 minutes, while the servers handling traffic from UK customers were refreshed. We don't expect any lasting impact or data loss from the slowness today. We will continue to monitor and watch the performance across all our regions worldwide.

We have identified an issue impacting access to LTI (LMS integrations - Canvas, Schoology) starting Mon 8/19 ~11:30am PT. Teachers and students can still access all Seesaw features through the regular app experience outside of LTI. We are pushing a fix for the issue today.

The issue is resolved and LTI (LMS integrations - Canvas, Schoology) should now be accessible again.

We’ve identified an issue for some students responding to activities and saving their work. We are working on a fix.

The issue has been identified and a fix is being implemented.

A fix has been implemented and we are monitoring the results.

This incident has been resolved.

We are currently investigating an issue where a small percentage of users are experiencing 500 errors across the site.

Between 1:05pm - 2:31pm pacific, Seesaw experienced an elevated level of API errors. We've identified that up to 2,600 schools and districts who are in the 'Seesaw Instruction & Insights' tier received a 500 error when accessing our site. We are working to restore their access.

A fix has been implemented and we are monitoring the results.

This incident has been resolved.

We are aware of reports of missing messages from the Seesaw application that impacted some users on May 8, 13, 14 for brief periods of time, approximately over a total period of 6hrs spread over those 3 days. We have identified the root cause and are working on impact metrics to recover any messages that are missing from / sent during the impacted time periods.

Due to an infrastructure outage, some users briefly saw an empty messages inbox in Seesaw. Some Seesaw users experienced this issue for brief periods of time between May 8 and May 14th, and we have since fixed the underlying issue. If you tried to send messages during this time, we recommend re-sending your message — you should be able to view and send messages as normal. We will continue to monitor and will also reach out to users who were impacted by this issue with further information.

Some iOS 17+ users (iPad and iPhone) have reported occasional crashes when creating complex drawings and using the eraser in the Creative Canvas. This is due to a change in Apple's iOS operating system, and we are currently working with Apple to resolve this issue.

Apple has fixed an issue in iOS 17.4 that was causing occasional crashes when creating complex drawings and using the eraser in the Creative Canvas. iPad and iPhone users on iOS 17.0 - 17.3 are encouraged to upgrade to iOS 17.4.

A small set of users are likely not receiving real-time updates in Messaging. The team is looking into this, and the current workaround is to refresh to receive new messages. Thank you for your patience.

We've confirmed that the issue has resolved itself. An upstream provider had an outage from 2/21/24 13:57 PT to 2/21/24 19:01 PT. Our logs show normal activity resumed by 19:15 PT, and we've made an improvement to prevent this issue from occurring if the provider were to have an issue again.

This incident has been resolved.
