Viedoc 장애 기록

Since the 4.95 release, Viedoc Me submissions have been recorded in the database using UTC time rather than the site's local time zone. If the UTC date and the site's local date differ at the time of submission, the Event date in Viedoc Clinic will incorrectly reflect the UTC date instead of the local date. Depending on the data entry windows defined in the study design, this may also result in out-of-window queries. The audit trail in the Viedoc Clinic UI, accessed via "Show History," displays the correct date and time stamp according to the local time zone. This issue affects both the current and legacy versions of the Viedoc Me application. The issue has been identified, and a fix is currently being prepared. The fix will ensure new submissions are stored using the site's local time zone, but it will not correct timestamps or out-of-window queries that have already occurred. These will be addressed in a future update.

After the Viedoc 4.95 release, when a revision is applied to a form containing a repeating item group, and a user upgrades the form from the landing page, data previously entered in the repeating item group is cleared. The issue is occurring on the EU and US training and production instances. Investigation is ongoing. Until further information is known, we advise all customers to refrain from applying revisions requiring form upgrades on forms containing repeating item groups.

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

We have received reports of intermittent delivery failures affecting text messages sent to numbers with country codes +31 (Netherlands), +32 (Belgium), +33 (France), and +44 (United Kingdom). An investigation is currently underway together with the subproccessor. The default SMS sender is changed from a phone number to "Viedoc" to reduce the risk of texts being treated as spam.

Since 10.30 CET today text messages are delivered as expected to numbers with country codes previously listed.

The User Administration Log (Excel) and Log of Users and Roles (PDF) cannot currently be generated for studies containing more than 100 users. This issue was introduced in the 4.90 release and affects all instances where version 4.90 has been deployed. The root cause has been identified, and a corrective fix is currently in preparation.

A fix has been developed and is currently undergoing testing. The fix is planned to be deployed as a hotfix.

This issue has been resolved with the release of Viedoc 4.90.1, which was deployed to all production instances on 2025-12-16. The User Administration Log (Excel) and Log of Users and Roles (PDF) can now be generated as expected, including for studies containing more than 100 users.

Since around 12.30 CET, 1st of December, Viedoc is not sending any emails from the EU and US training and production instances due to a service disruption. The issue has been identified and we are working with our subprocessor to resolve the issue. All emails triggered during the affected period have been queued and will be delivered. The incident is caused by a malfunction at one of our subprocessors.

The email queue is currently being processed, and messages are being delivered, although with a temporary delay.

The queue had been fully processed at around 9.20 PM CET on 2025-12-01. Since that time emails have been delivered without delay.

The planned release of version 4.89 to the CN training and production instances has been cancelled due to unforeseen technical issues specific to the Chinese server environment. As the 4.90 release is already scheduled for December, we will proceed directly from version 4.88 to 4.90 for the CN training and production instances. The impact to end users is minimal, as version 4.89 contains only non-critical bug fixes. No other instances or regions are affected by this change. We appreciate your understanding and apologize for any inconvenience this may cause.

From approximately 23.44 UTC to 23.54 UTC, users faced issues logging in to the European production instance. Investigations to find the root cause are ongoing. No other instances were affected.

Description From approximately 23.44 UTC to 23.54 UTC on 2025-11-02, users were unable to log in to the European production instance. It is possible that users faced sporadic issues logging in also between approximately 23.00 UTC and 23.44 UTC. No other instances were affected. ‌ Cause The cause of the issue was an unexpected error in the identity provider \(idp\), leading to an accumulating memory consumption during the evening \(UTC\) of 2025-11-02. From approximately 23.00 UTC users would face sporadic failures when trying to log in. From approximately 23.44 UTC users could not log in. At 23.54 UTC on 2025-11-02 the idp was restarted, and users could log in as expected again. ‌ Corrective Action Alerts were triggered when the idp did not respond and the idp was restarted again at 2354 UTC on 2025-11-02. After the restart users could log in as expected again. ‌ Preventive Action Preliminary investigation identified a few improvements that could be made to make the idp more resilient. Implementation of these improvements have been initiated while the investigation of the issue continues.

Emails triggered from EDC actions in Viedoc has been failing sporadically on the EU production instance since approximately 9AM CEST 2025-09-02. No other instances are affected. Investigations are ongoing.

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

A fix has been implemented and emails are now being sent as expected. We will continue to monitor the situation.

Since approximately noon CEST, emails triggered from the EDC has been delivered as expected.

**Description** Between 9AM CEST on 2025-09-02 and noon CEST 2025-09-03 there were sporadic failures in email alerts expected to be triggered from Viedoc on the EU production instance. No other instances were affected. Customers were initially informed through the status page at 15.56 CEST on 2025-09-03. ‌ **Cause** On Tuesday at 9AM CEST on 2025-09-02, there was a very high load on the system. The high load on the system caused worker function apps, used to handle various processes  in the EDC, to scale out to the maximum use of 20 instances in parallel. This caused failures, and in combination with in-built retry policy of failing actions, there was an overload on the system. While form save and form view continued to work as expected throughout the duration of the issue, there were sporadic errors in specific system actions in the post-processing step. * EDC email alerts, configured in the CRF design, were sporadically not sent during this time window. It did not affect all emails. * Terms defined to be coded in the medical coding tool sporadically failed to sync to Viedoc Coder. It did not affect all terms. ‌ **Corrective action** Once the root cause of the exceptions was identified, the worker function app was gradually scaled down to run on 4 instances to avoid having too many actions ongoing at the same time. This work begun around 11AM CET on 2025-09-03 and an immediate improvement could be seen. Around noon 2025-09-03 the situation was completely resolved, and all emails could be sent as expected again. ‌ Email alerts not sent during this issue could not be re-sent and will also not show up in the communication log. ‌ All terms that had not synced properly with Viedoc Coder during the issue, were synced with Viedoc Coder on the afternoon of 2025-09-03 and 2025-09-04. ‌ **Preventive action** Scaling down the worker function app to run on 4 instances is not considered to bring any noticeable impact on performance, but will ensure the same overload issue will not occur again. An evaluation will be performed if it is necessary to scale up the worker function app again and if so, how this could be done without causing any similar issues.
