On Sunday, September 15th at 01:32 UTC, orchestrator and other component jobs started failing in the EU region. In the following hours, our worker servers weren't able to handle the workload, and the job backlog started to increase. We manually resolved the incident, and the platform was in full operation with a clean backlog at 08:26 UTC.
Once we discovered the incident, we replaced all our worker servers and added more capacity to clean up the backlog faster.
We are also working on a completely new job processing and scheduling mechanism that will prevent similar issues from occurring down the road. We sincerely apologize for the inconvenience caused.
Few orchestrator and transformation jobs were restarted on September 16, 06:36 UTC.
This was caused by issue in zone rebalancing. We apologize for the inconvenience.
]]>We are investigating job failures in EU region started at 1:32 UTC.
We will provide an update when we'll have more information.
UPDATE 06:06 UTC - We have identified the issue and fixed the cause. Backlog is processing now.
UPDATE 07:54 UTC - There is still backlog of orchestration jobs. We have increased the processing capacity. It should be cleared in half an hour.
UPDATE 08:26 UTC - The backlog was cleared. All services are running.
We apologize for the inconvenience, we'll share more details in a post-mortem.
Support for deprecated GoodData Writer v2 is coming to its end, the writer will be shut down on September 30, 2019 .
If you are still using the old Writer you should see a deprecation notice in Keboola Connection. Please proceed to migration.
If you need any help migrating the writer, contact Keboola support.
This is a reminder that the Deprecated OAuth broker will be shut down on September 30, 2019.
Please start the migration if your projects aren't migrated yet. If you have any questions please contact Keboola support.
We are experiencing some jobs failures and timeouts in the US region due to a shortage in one availability zone in the Amazon Elastic Compute Cloud service. We are going to monitor the situation and keep you posted.
UPDATE 15:48 CEST: Apparently it has some overlap to other AWS services too because login to Developer Portal (which uses AWS Lambda and Cognito) timeouts intermittently.
UPDATE 15:54 CEST: AWS confirms that some EC2 instances are impaired and some EBS volumes are experiencing degraded performance within a single Availability Zone in the US-EAST-1 Region. Some EC2 APIs are also experiencing increased error rates and latencies. They are working to resolve the issue.
UPDATE 16:37 CEST: The works on resolving the issue are still in progress.
UPDATE 17:06 CEST: The impaired instances and EC2 APIs are being recovered. AWS support continues to work towards recovery for all affected EC2 instances.
UPDATE 18:04 CEST: Recovery is in progress for instance impairments and degraded EBS volume performance. On our side, it looks that the problems more or less disappeared an hour ago and the platform is back to normal.
]]>On 2019-08-15 12:23 UTC, we deployed a broken version of Keboola Connection. It prevented some users from accessing their projects. The problem was fixed at 13:01 when we rolled back to a previous version. We sincerely apologize for interrupting your work and wasting your time.
There was an error in a permission check, and only users with the permission to create a project were allowed to enter a project. Such a scenario is not covered in the functional tests, and the situation was overlooked during peer review of the change. As soon as we identified the problem, we immediately deployed a previous version of Keboola Connection. That itself took about 15 minutes.
We're extending the software tests to include more scenarios.
We're also updating monitoring alarms to make sure that we know about a problem before you tell us through our support channel.

Google Drive verification issue in the EU region has been resolved.
In the input mapping of Snowflake transformations, the TIMESTAMP data type now defaults to TIMESTAMP_NTZ.
Terminated job is colored in the same way as a terminated label.
There is an issue which causes a 404 error (Page not found) to be displayed after login. We're working on a fix, which should be ready shortly.
The issue affects only log-in of certain users on the UI. Jobs running inside projects are unaffected.
Update 13:01 UTC: The problem is fixed. We apologize for the inconvenience, we'll share more details in a post-mortem.
Since July 26 2019 there was an issue with authorisation of our Google related components using OAuth in the EU region.
We needed to undergo a verification process of our apps by Google. This process has been recently made more strict and we weren't able to finish it before the deadline.
We are very sorry about this, we should have paid more attention to this process and the consequences related to not complying with it.
We have now successfully verified most of our Google components. We are still waiting for the verification of GMail Extractor and GMail Attachments Extractor.
Today, 30.7.2019, 18:30 CET we noticed errors when creating projects using promocodes via https://try.keboola.com. We rollbacked app to the previous version and everything is working now. Moreover we continue investigating the cause of the error.
]]>We are investigating a Google Drive Extractor authorization verification issue in Keboola Connection EU.
Only creation of new configurations is affected.
We will provide an update as soon as the issue is resolved.
Update 2019-08-14: The verification issue is resolved and new configuration are working again.

Some of our users experienced errors in Keboola Connection (in both regions) yesterday when saving configurations of several components.
An error was displayed to users who tried to save their configuration between Jul 9, 2019, 12:35 CET and Jul 10, 2019, 14:18 CET.
Mainly users who have an older version of Chrome Browser or any version of the Firefox browser were affected.
The issue was caused by wrong response headers (unsupported by the mentioned browsers) being sent to a preflight request on one of our API services.
We sincerely apologize for the inconvenience caused.
]]>Three weeks ago we announced the start of Keboola Connection redesign.
We're glad we can share another important update with you.
This allows you to more quickly navigate within a project and should improve user experience. All sections remain the same and the content hasn't changed.
We hope you'll like this update as much as we do.
]]>Zendesk is down, so our support system is inaccessible. Keboola Connection is unaffected, but if you run into anything critical, please reach us via email.
We'll update this post when we obtain more information.
Update 14:36 UTC - Looks like things are back to normal now.
]]>There's a new option in organization-level settings which allows you to require Multi-Factor Authentication for each member of your organization and project.
Users not having the Multi-Factor Authentication enabled will be prompted to enable it.
When setting data types in transformation's Input Mapping you can set same data type to all columns at once.
When configuring tables in GoodData writer, we try to look for metadata for columns and set types for you automatically.
Translates text into any supported language.

New component which uses Google Cloud Natural Language API to extract text features using pre-trained machine learning models.
https://components.keboola.com/components/kds-team.ex-google-nlp
The old version of GoodData Writer (v2) was already unpublished a few months ago and does not allow you to create new configurations since then. Now the time has come to deprecate the component entirely and set a date for its final shut down.
The date is September 31, 2019, so you are encouraged to migrate old configurations until then. The ui shows a deprecation notice and offers you to run the migration process.

Today, Thursday 20, 2019 from 02:02 CET, one of our job workers became unresponsive.
This resulted in some jobs taking longer to process as they had to wait for one of the other available workers whose workload had increased as a result.
The affected instance was replaced at 15:50 CET and we are working on improving the automated detection of such failures.
Thank you for your understanding.
Many of you have noticed that our website was redesigned a few months ago. We have been continuing to prepare and apply a new design to all remaining parts of our system:
Four months ago, we introduced the Refined Storage Console, even though the main point of the changes was to remove old code. Four weeks ago, we started using the Roboto font in Keboola Connection and Developer Portal.
We're now happy to announce that the first part of the redesign has been applied to all pages you see during the authentication process.
The authentication process itself wasn't affected by the changes and you should be able to go through it with ease.
There are many more things to come from us. We're already working on the second phase of the redesign. Stay tuned.

Update 12:36 UTC:
Everything should be back to normal. We'll keep monitoring our systems.
Update 9:15 UTC:
You should not experience any more errors, but things are a bit overloaded so longer execution and waiting times are expected. Thank you for patience.
Update 7:52 UTC:
Snowflake services restored. We're resuming processing of jobs.
Update 6:23 UTC:
Snowflake services are still not restored. We're slowing down job processing, so you'll see a much larger amount of queued jobs. EU region is unaffected.
Original post:
Some Snowflake queries started failing around 03:14 UTC which is causing errors in job processing. Failures are caused by incident which is currently investigated by Snowflake https://status.snowflake.com/incidents/0sjfn3d5jq2q .
We will provide an update as soon as the issue is resolved.
Description and custom data type can be provided for each table column in Storage. Custom data type allows you to override data type provided by the system. These data types are then used as defaults for transformation and writer table inputs.
You can explore and edit these values on Storage table detail.
An alias can be created from another alias. Also aliases created in Shared Buckets are propagated to linked buckets and can be further aliased. This simplifies data preparation and sharing, tables which don't require additional processing can be directly aliased to shared buckets.
Chaining is supported only for aliases with automatically synchronized columns and without filter.
With automatic incremental processing, the component will receive only data modified since the last successful run of that component.
For Jupyter and RStudio sandboxes, code templates can be defined. Code templates can be set for a given user or for the entire project. A Jupyter template is a notebook file (.ipynb). An RStudio template is a simple text file. If a sandbox is loaded from transformation, the transformation code will be appended after the template code.
One of our core databases in US region has been restarted due to some failures by AWS. All running jobs failed or will fail due to this reason.
UPDATE: The problem affected ca 26 jobs. There was some unspecified low-level failure on the database or its underlying hardware and AWS automatically switched to a backup instance. We are going to investigate if our platform can handle the failure and restart the jobs automatically next time. Thanks for your understanding, we are sorry for any inconvenience.
]]>Today, on April 13 2019 from 14:14 UTC to 14:15 there were some orchestration failures in the US region due to an internal system upgrade. Very few orchestrations were affected, please review your orchestration and restart if needed. This issue is not related to the issue with failing orchestrations happened previously today.
]]>[2019-04-13 8:20 CET]
We are registering increased amount of failing orchestrations since 2:27 CET. We are investigating the issue now and will keep you updated.
[2019-04-13 8:45 CET]
We traced down the problem and fix it. Everything seems to be working now, we continue monitoring it. Please review your orchestrations and restart them if necessary
