Scheduled Maintenance FAQ

Between 8am and 12 noon on Saturday 22nd November 2025 UK Time, Kleene will conduct scheduled maintenance during which time the Kleene platform will be unavailable.

What are we doing?

Kleene is performing database maintenance. This is part of our ongoing commitment to providing you with the highest level of service and high performant environments.

During the maintenance process, it will be necessary for us to temporarily stop our current systems in order to take backups and progress with maintenance.

While we anticipate that the maintenance process will be seamless and without disruption to our services after the maintenance window, unexpected issues may arise. In the event that things do not proceed as expected due to the maintenance, please rest assured that we will prioritise the resolution of any issues promptly and efficiently.

We understand the importance of maintaining the highest standards of availability and reliability, and we appreciate your understanding and cooperation as we work to implement these enhancements.

When will this maintenance happen?

The date of the maintenance is 22nd November. We will be in touch ahead of this date with reminders of the upcoming service disruption. Please stay tuned for updates.

What do I need to do?

There's no action required from Kleene customers at this moment.

Will there be any downtime?

The maintenance window is Saturday 22nd November between 8am and 12noon.
This means that Kleene will be inactive during this time. The reason for this is that the maintenance includes stopping any live transactions to the backend database.

🚧

You will not be able to log into your Kleene account during the maintenance window.

What to expect during maintenance ?

Kleene services will be stopped completely during the maintenance window. It is expected during the downtime that any scheduled extracts and transforms will not execute. Any extracts or transform that are scheduled to start before 8am, but continue running into the maintenance window will be affected. However all extracts and transforms should run on their next existing schedule after the maintenance maintenance window finishes.

📘

If it can be avoided, please do not update your existing schedule so that your full pipeline runs before the maintenance window. Doing so may impact the performance of the system, therefore impacting already scheduled runs.

This maintenance does not include any changes to Kleene’s existing features or functionality.

What to expect after maintenance ?

All functionality should work as expected. All scheduled extracts and transforms will run as per their schedule following this maintenance.

What will happen to extracts that bring in data for one day only?

(This advice is for extracts that load 1 day’s worth of data each day)
Please note that the below advice is based on standard configuration and the outcomes may vary depending on your extract configuration.

• Append
  After missing 1 day of data - 2nd day will extract that day’s data and append to destination table
  1 day will be missing
• Append Incremental
  After missing 1 day of data - 2nd day will extract all data between the last date in destination table to that day’s data and append
  0 days of data missing
• Drop Create Load
  After missing 1 day of data - 2nd day will extract that day’s data and load to fresh destination table
  1 days will be missing
• Truncate Load
  After missing 1 day of data - 2nd day will extract that day’s data, clear the destination table and load into it
  1 day will be missing

What can you do to backfill any missing data?

Backfill tasks will be needed for the missing days

• Check the connector docs to see if backfill window is possible, this should give you specific details on each of your connectors.
• Extract the missing days and insert into the destination table
• Once data is restored, transform runs will generally pick up the missing data and update the pipelines

However there are some Connectors that do not facilitate backfill windows e.g. Google Ads, True-fit-360, Tik-Tok (display)

Transforms that are configured to work for the present day will be affected and might need to be run manually to cover the data from Saturday 22nd November.

Will my data be safe during the maintenance?

Yes, data security is our utmost priority. The maintenance includes our database maintenance and there are no changes scheduled to data sources or warehouse.

What happens in case something doesn’t work?

In case of any unforeseen issues during the maintenance, a roll back plan is in place.

Roll Back Plan for Migration

if there are problems at any point during the 4 hour maintenance window, we will execute a roll back to the previous state.

Roll back plan on the day of maintenance

We will restore the backed up snapshot of the database. However, any scheduled run missed during the maintenance will still be affected. In the event of roll back, we will capture the results for analysis and work towards a maintenance date in the future.

Kleene has a rigorous testing process already in place, this means that we are well placed to run tests to validate the maintenance.

Who can I contact if I have questions?
