Each month Eficode does a monthly maintenance break at a predetermined time window. While we aim for continuous delivery, during the maintenance break the services might be down. During these breaks we install all security patches (if they haven't been installed earlier) and upgrade service components to new versions. We sends a list of changes a week before scheduled maintenance to listed persons.
Example of the e-mail
Additionally we release our change highlights in our websites e.g. https://www.eficoderoot.com/release-notes/
Critical security updates
Eficode follows the public and private streams for security related to all environments. When we gain information on a vulnerability we inform our customers the exact time the patch time or mitigation has been applied. If the problem is not catastrophic we aim to install these after business hours. We also send a list of changes ASAP to relevant persons.
