# Incident Summary On Friday, March 27, 2026, Capsule experienced several periods of slow performance and some temporary outages. These were caused by two separate and unrelated issues: * A recent software update that unintentionally caused parts of the system to become stuck. * An uncommon data pattern which led to degraded performance under specific conditions. Both issues have now been resolved. The first was fixed by rolling back the recent update, and the second by mitigating the data pattern that caused the issue. At no point was any customer data impacted. # Timeline of Events _\(All times are UTC\)_ * **00:01** – A small number of users began experiencing errors when using the web app and API. * **01:00** – Errors increased significantly, triggering an alert to our on-call engineers. Investigation began. * **01:35** – The team observed locking behavior and replacement servers deployed to mitigate. * **02:09** – Service appeared stable, with further investigation ongoing. * **08:37** – Errors reappeared for a small number of users. * **08:46** – Errors increased again, and engineers were alerted. Initially thought to be a repeat of the earlier issue. * **08:54** – Initial fixes were applied, partially restoring service. * **09:12** – The earlier issue was fully identified and fixed by reverting the problematic update. * **09:34** – While monitoring the fix, a second issue was observed. * **09:54** – The cause of the second issue was identified, linked to an uncommon data pattern. Fixes were applied and service was restored. * **12:30** – Reprocessing this data caused another spike in errors. * **13:00** – Mitigation put in place for the data pattern, and full service was restored. # Next Steps We are carrying out a full internal review of both issues. Based on this, we will introduce additional safeguards to prevent similar problems from happening again.

This incident has been resolved.

We're very sorry if you suffered from the periods of slow responses and elevated error rates with Capsule yesterday. We’ve tracked the issue down the a bug in our data stores query optimiser that resulted in what should have been a fast responding query taking several minutes to complete. This only happens in rare situations with an unusual configuration of data. While we fully understand the exact nature of the optimiser bug we have applied a fix that stops the bug from occurring. Once again we’re sorry for this disruption this caused.

We're currently aware of an issue affecting some BT Broadband customer's access to Capsule. BT appear to be working on a fix.

Some users of our Gmail Add-on may be experiencing delays between messages being received in Gmail and stored in Capsule. We are currently investigating and will provide an update shortly.

We have identified the cause of the delayed message storage and mitigated it. No messages have been lost during this incident but a backlog has accumulated. Messages are now processing at normal speed and we expect to be caught up soon. We'll continue to monitor and provide an update once it has cleared.

The backlog of messages has now cleared and new messages should be store without delay. Apologies for this disruption in your day. We'll be seeing what mechanisms we can put in place to avoid this in the future.

Some users may be experiencing a delay in the storage of emails using our Drop Box feature. This was due to a server failure. All messages sent to the Drop Box should have been queued for processing during this time but may take some time to appear in Capsule due to a backlog that has accumulated. We are currently monitoring and will update once the backlog has been processed.

The backlog of queued messages has now been fully processed and the time taken to store new messages using the Drop Box should now be back to normal. Although these incidents are rare we are actively working on a solution to make the Drop Box more resilient. Apologies for the disruption in your day.

From 02:16 UTC April 2nd to 13:52 UTC April 14th around 10% of our Gmail Add-on users will have experienced increasingly long delays between messages being received on existing stored conversations in Gmail and them appearing in Capsule. This was due to a processing issue which we have now resolved.

_From 02:16 UTC April 2nd to 13:52 UTC April 14th around 10% of our Gmail Add-on users will have experienced increasingly long delays between messages being received on existing stored conversations in Gmail and them appearing in Capsule. This was due to a processing issue which we have now resolved._ We know a large number of our users have come to rely on our new Gmail Add-on and we’re extremely sorry it hasn’t been working to the usual high standard you would expect from a Capsule feature. Therefore we feel it’s only right to provide a more detailed explanation and assurances that we’re working to prevent this from happening again. First a little background - Over the past two weeks we were receiving sporadic reports from our users that our Gmail Add-on wasn’t storing new messages that were part of an existing stored conversation. We immediately began an investigation into the issue and identified a potential cause. This related to a timeout inside our code that communicates with Gmail. A fix for the timeout and some additional logging to assist with the investigation was rolled out. We then asked some of the users affected if the issue was resolved for them. It quickly became apparent it was not. At that point we started analysing the additional logging we had put in place to see if there was any pattern to the reports we were receiving. The analysis was still ongoing on Friday \(April 12th\) when we noticed a sudden unusual size increase in one of a number of queues which forms part of the processing for our Gmail Add-on. The queue is a stream of events we receive from Google for a subset of user mailboxes which has our Gmail Add-on enabled. We consume these events so we know when something has happened on a stored conversation i.e. a new message is sent or received. When we receive an event for a stored conversation we request all the updates since we last fetched the history of it and store any new messages that have occurred since. The increasing queue size suggested we had an issue processing the event stream which could easily have accounted for the missing message reports so we focused our investigation on that. After a short time we identified an issue fetching conversation histories from a single user’s mailbox. The fetch from Gmail was taking an abnormally long time and hitting a transaction timeout we have in our code. In an effort to recover automatically, our code re-attempted the fetch. This caused an infinite loop that we didn’t recover from. Unfortunately this effectively stalled the processing of the event stream from Google for the users sharing the same queue as that user. Once we found this loop, we disabled the Gmail Add-on for that single user and restarted the process which consumes the event stream. This kicked off a recovery processing a backlog events. This recovery took a number of hours due to the volume of events which had built up. After the backlog was processed we confirmed that new messages that were part of an existing stored conversation were being processed and stored in near real time once again. We’re now in the process of introducing additional monitoring and alerting so we are made aware of any delays in processing. We’re also introducing additional safeguards to ensure an issue with a single user doesn’t impact other users sharing the same queue. And finally we’re looking at how we can re-architect the solution to ensure that if another backlog of events ever does form we can process through it as quickly as possible. This was quite a challenging incident for us and we’ve learnt a lot from it. Once again we’re extremely sorry for the impact this had on our users and please be assured that we’re working hard to prevent it happening again.

We are aware of an issue for which may mean you are temporarily unable to view or add files in Capsule. This will affect emails sent to the Capsule drop box as well. In addition, profile pictures might also not be displaying for you. This appears to be affecting other services hosted by our provider. We are continuing to monitor the situation and we'll post an update once we have more information.

Our hosting provider believe they understand the root cause of the problem and they're working hard to get it fixed. We're still monitoring their progress closely and will keep you posted on any more updates.

We’re starting to see some improvements around viewing and uploading attached files and icons & profile pictures are slowing coming back as well. We’re still waiting for everything to be 100% resolved before we can get the Capsule drop box up and running again. As always we’ll let you know.

Our hosting provider is reporting that they are fully recovered and that the file storage service is operating normally. Access to files, pictures and icons in Capsule is back and so is the ability to upload files. The Capsule drop box is also back in action and it's currently going through the backlog. It won't be long before everything is back to normal.

Our hosting provider has given the all clear and Capsule is back to fully operational. File upload is back and the drop box is humming along nicely. Thanks everyone for your patience during all this. We hope it hasn't caused too much trouble.

We’re seeing reports that a small number of users are having trouble logging in to Capsule or are getting a 504 error. We’re in the process of getting this resolved and will let you know as soon as everything is back to normal.

Capsule is back to normal for everyone now and we’re monitoring the situation closely.

Some users may have experienced degraded performance between 2:30pm and 2:54pm UTC as a result of an issue with a server. Very sorry for the interruption. We’ve resolved the issue and everything is back to normal again.

Over the weekend an update to the LastPass Chrome extension has introduced a bug that is causing unexpected logouts when attempting to complete forms or perform actions in Capsule. While we work with LastPass to help them fix the extension we suggest disabling the LastPass extension or switching to an alternative browser like Edge, Firefox or Safari.

We have not been able to get satisfactory assurances that LastPass will be able to resolve this issue with their extension. However in the meantime we have been able to create a workaround to resolve the issue by making changes to Capsule. If you're currently logged into Capsule, you'll need to log out then back in again. You'll then be able to use Capsule as normal with the LastPass extension enabled.
