During the last 2 days Kolab Now has experienced a serious performance degradation issue. Users see that logins to- and operations in the webclient is taking a long time, and users connecting via desktop or mobile clients might not be able to perform synchronizations.
In the end of Wednesday it was thought that the root cause was found, and many users saw better performance for a while, but Thursday morning the performance dropped back to unacceptable levels.
This Friday’s service window was being executed well, and while assisting in replacing some old infrastructure, it opened opportunities to proceed down the same track. With that in mind, the Kolab Now operations team will perform more maintenance on the infrastructure of the Kolab Now platform on Friday, 27th of January 2023 at 10:00 UTC. The update will move more of backend services to newer infrastructure. No new features visible to end users will be enabled during this maintenance.
The service window is expected to last for no more than 4 hours, ending on Friday, 27th of January 2023, at 13:00 UTC.
On Saturday January 14th, 2023, from approximately 03:47:12 UTC a group of Kolab Now users observed an error stating: “Gateway time-out” when trying to login to the webclient, the dashboard, or connect with any desktop or mobile client. The Kolab Now main page https://kolabnow.com/ and all other services (Support, blog and knowledge base) were available with no issues for these same users.
The issue lasted until approximately 08:04:22 UTC, and was caused by a db server in one of the clusters being stuck in a large operation. The issue caused troubles with the login procedure, but had no impact on the mail flow. No mail was lost or delayed during the incident.

Another year past and we needed to again refresh our certificates.
As in previous years, e.g. 2018, 2019, 2020, etc, we rolled over certificates across all systems over the last few days of the year.
The new certificate is in place, and applies to https://kolabnow.com/, imaps://imap.kolabnow.com and smtps://smtp.kolabnow.com.
As in previous years, we publish the fingerprint here:

Ho ho ho,
what a wild, crazy and yet beautiful year we shortly leave behind us!
Again we want to express our deep thankfulness to all the users of Kolab Now – you guys rock and help us everyday to improve, refine and grow.
In the last year we had ups and downs, learned from mistakes, developed new paths where necessary and we say: respect for everyone going through this together with us and trusting in our expertise. Your feedback and use of our services made it possible for us to push Kolab Now to yet another higher level of quality. We can now with great pride say that:
KOLAB NOW ROCKS!
In a year like 2022, one realize how important it is to be able to stay in contact with people in your close circle as well as the ones who are on a greater distance. Some people move away and some work in remote places. No matter how personal or professional the contact is, it is important that it can be kept private and secure.
Here is the perfect holiday present from us for the one with whom you want to stay in contact in 2023:
New Kolab Now sign-ups (individual and group accounts) will receive 3 months free usage when signing up before the 01.01.2023 with the voucher code KOLABNOWROCKS2023
Here is how it works step by step:
Merry Christmas and a Happy New Year from the Kolab Now team!
Kolab Now offers a mail filtering feature. That makes it possible to apply a series of actions to specifically selected incoming emails, so that incoming mail meeting a certain criteria can be automatically processed by the server and handled/organized according to the defined actions. For example the server can move the message to a specified folder, redirect it to another account, send a reply, discard, delete, etc for as long as the defined criteria is fulfilled.
This goes out to those users who joined our service back in the days when it was still called MyKolab.
(Note: No emails were hurt during the writing of this blog post)
In 2015 our service changed its name from MyKolab to Kolab Now – as we know it today.
On Monday June 06 2022, from approximately 11:24 UTC a group of Kolab Now users observed an error stating: “Gateway time-out” when trying to login to the webclient, the dashboard, or connect with any desktop or mobile client. The Kolab Now main page https://kolabnow.com/ and all other services (Support, blog and knowledge base) were available with no issues for these same users.
The issue lasted for about an hour, until approximately 12:19 UTC, and was caused by a db server in one of the clusters being stuck in a large operation. The issue caused troubles with the login procedure, but had no impact on the mail flow. No mail was lost or delayed during the incident.
The operations team was warned by the monitoring system about a stuck db server in the cluster, and was having hands on keyboards right away. The issue lasted for about an hour (some users in the group saw return of service earlier than others), and was caused by this db server in the cluster being stuck in a large operation.
Further investigation and action is going into reevaluating the amount of resources assigned to the db clusters and other servers for such large operations of this type.
If you were among the group of users that was impacted by this, then please accept our apologies for any inconvenience caused.
For all the fellows out there who are interested in our product and service we would like to explain today again the difference of individual & group accounts and prices that apply.
