On Saturday, 31st of July 2021 we added a few features to Kolab Now during a service window. We already informed you about two of the features that were added; the user controlled Sender Preferred Framework (SPF) for group admin users, and the user controlled opt out of the greylist for users. What we failed to update you on was another added ‘new’ payment option: Bank transfers.

Announcing Service Window: Updates to Kolab..
This Saturday, 19th of June 2021 at 09:00 UTC, the Kolab Now operations team will perform an update of the Kolab software on the Kolab Now platform.

Incident Report: IMAP backend server out of memory
On Monday night, the 7th of June 2021 @ 18:29 UTC, a process on one of our many backend servers was taking a lot of memory; faster than it could release it again, which made the server run out of memory and stop responding. The server were serving IMAP for a limited group of users, who in turn were impacted by the incident
As the server was heavily monitored, alarms were going off with the staff, but was little noticed, as it happened in a low traffic period, and as the systems are build to fix such situations themselves. The systems in this class usually just restore and keep working. This time however, the server did not come up in a timely manner, and the mentioned users saw their mailboxes freeze and their mail become unavailable.
The staff realized that something was not as it should be and went on to manually restore the situation. At 20:27 UTC the server was back up and running, and all mailboxes were available again.
No data was in danger, and mail delivery to the impacted mailboxes continued during the incident.
We apologize for any inconvenience that this incident may have caused.
Announcing Service Window: Update of firmware on Storage
This Saturday, 5th of June 2021 at 09:00 UTC, the Kolab Now operations team is performing an update of the firmware on the storage canisters in the datacenter. As Kolab Now is running the operations on high class professional IBM servers under great warranty (see the knowledge base article), the update will be performed under advice from the IBM technical support crew.
As the storage system is 100% redundant, we expect that there will be no interruption or downtime – planned or unplanned – in connection to this change. Users can follow the status of the change via the Kolab Ops Twitter account. They can keep working and collaborating online as usual.
Should you have any issues in this or any other context, then please contact Kolab Now Support
UPDATE 2021-05-05 @ 11:00 UTC: The update has happened, and as expected, there was no downtime. All systems are back up and running as they should be.
Incident Report: Network Interruption
At 06:00 UTC on Wednesday May 26th Kolab Now fell silent. All connections were dropped. What happened?
Kolab Meet beta – The story so far..
Earlier this year we wrote here on this blog about our new added feature: ‘Kolab Meet’ The voice & video conferencing tool. We explained how this tool was still in beta, but that all users of kolab Now (with full groupware subscriptions) could gain access to the tool, and how it was used.
Now it has been a while, and we have made a few updates to the tool. It is still in beta, but we have added features and fixed some defects and corrected some inconveniences. here are a few comments on experiences with the latest iteration of Kolab Meet (listed in no particular order):
Incident Report: Lock down of firewalls
At 10:10 UTC this morning, Wednesday April 28th, parts of our environment were getting updated. The updates included Security Enhanced Linux configuration on one layer of our firewalls. Unfortunately this new configuration locked up these firewalls and all traffic was blocked for a group of users.
The problem was confirmed corrected at 10:36 UTC.
No data was in any danger of being compromised during the incident.
We apologize for the inconvenience.
Welcome to Kolab Meet – Our new Voice & Video conference…
For some time, users asked us if we could create a Voice & Video Conferencing tool, and apply the same level of privacy and secure communication strategy to it, as we do with everything else that we do. A certain virus, a rise in home office activities and the popularity of online ‘after work’ partys made the request even more compelling; we re-focused our efforts to this task, and here is the result.
Our Statistics for 2020
Our terms of service state there’s basically no way for anyone to get any access to your data without us also being able to talk about the fact it happened.
Like the last time we declared having made a full eclipse around the sun at an arbitrary date, here’s our statistics for 2020.
