  • To simplify the process around installation of security patches and ECDN server version upgrades, you will now be able to define a recurring maintenance window in the ECDN portal. At the designated time, automated scripts will be run to install the updates. This rollout will be done in three phases.
  • Phase 1: Backend upgrade - Today.
  • Phase 2: Update all customer ECDN server instances - January 10 to January 18. See below for details.
  • Phase 3: Portal upgrade - January 22. See below for details.
  • Backend services:
    • Added: Support for automated ECDN server upgrades.
    • Fixed: Changing midgress regions in the portal did not trigger server configuration updates.

 

  • During this maintenance window, playback will be affected for all customers for up to 20 minutes. Access to the Portal will not be affected.

  • This is the second phase of the automated maintenance window release rollout. In this phase, like before, we will ask you one more time for a maintenance window to upgrade all the existing ECDN server instances to the latest version. After this server upgrade, all subsequent upgrades can be done as per an automated schedule.
  • Virtual appliance:
    • Added: Support for running upgrade scripts as per a specified schedule.
    • Added: New self-test scripts added to check test NTP server connectivity and clock drifts. The results will be displayed in the portal as health status indicators.
    • Added: New self-test scripts added to check connectivity to all end points required to install software upgrades. The results will be displayed in the portal as health status indicators.
    • Fixed: Remote assistance VPN connectivity is checked to have successfully established a connection before returning a success result. This fix will make the status display in the portal more reliable.
    • Fixed: Cache file system out-of-space issue.

 

  • During maintenance window you specified, while your servers are being upgraded, all playback will be affected. Access to the portal will not be affected. You will see gaps in the performance metrics for the duration of this upgrade window.

  • This is the third and final phase of the maintenance window release rollout.
  • Portal:
    • Changed: A new version number scheme for ECDN servers. Major. Minor. Sub-minor (Date). The date reflects the most recent date up to which all known operating system security patches that have been installed.
    • Changed: After login, the first page displayed will be the servers list page. Previously, the locations list page was displayed. This will allow you to right away see the status of all the ECDN servers.
    • Changed: In the top menu bar, first item will now be Servers (now a dropdown widget). Locations has been moved to the right.
    • Added: New "Software updates" menu item under "Servers" dropdown in the top menu bar. This page will allow you to set a recurring maintenance window for automated server upgrades. You can also see a list of all the servers that are not running the latest version along with a status indicator of whether they meet the required connectivity requirements.
    • Added: On servers details page, new status indicators to reflect the health and connectivity of the ECDN servers. The additions are: Remote assistance connections and NTP server connections. Existing status indicators have been enhanced to show the results of new self-tests for ensuring this server: has a valid SSL certificate, has a stable connection to upstream content server (midgress or parent server), and a stable connection to the Software update sites.
    • Fixed: For locations, setting a parent node or specifying an upstream midgress regions has been merged into a single setting. For the "Upstream source" value, you can now pick a midgress region or a parent ECDN location.
    • Fixed: Reports request page does not correctly account for DST changes.
    • Fixed: Changing midgress regions in the portal did not trigger server configuration updates.

 

  • During this maintenance window, playback will NOT be affected. There may be momentary outages while accessing the portal.

  • Virtual appliance:
    • A new version of the virtual appliance will be released to make ECDN servers compliant with GDPR regulations. We strongly recommend that all new installations of ECDN servers use this version going forward.
    • All existing ECDN server instances will need to be upgraded to bring them into compliance. All upgrades MUST be completed by May 15, 2018 in order to be compliant.
    • No actions are needed from customers side. IBM ECDN team will do these upgrades. IBM Cloud Video support team will work with each customer to identify a mutually convenient 3 hours maintenance window to do these ECDN server upgrades. During the upgrade, there will be downtime. Each server is expected to be down for less than 5 minutes. All ECDN servers belonging to one customer will be upgraded within a single maintenance window.
  • Other changes:
    • [backend] Fixed. Now location configuration changes are first saved in the ECDN database, before updating the other backend SDCDN service. There is no longer any timing related ambiguity in the net outcome. As a result, after making updates to the external IP address settings for a location in the ECDN Management portal, users now no longer have to disable/enable each server in that location for the changes to go into effect.

  • Persist recorded videos contents in ECDN server cache to disk. Previously all cache content was in memory, and was lost after a server reboot. Existing ECDN server instances will need to be upgraded to enable them to use this new feature. Upgrade will require the ECDN servers to be rebooted. ECDN operations team will do this upgrade and reboot. This is an optional feature. Even after existing ECDN servers are upgraded with this new release, you will need to make additional changes manually on the host hypervisors to enable cache persistence to disk. You don't have to immediately do the manual steps. You may delay them as per your convenience and when you are ready to use this capability.
    • All contents in the cache disk will be encrypted .
    • Only recorded video playbacks are cached to disk on first use. Live broadcast stream contents are cached only in memory.
    • Minimum recommended size of the cache disk is 4GB.
    • Management Portal displays on the server configuration page new controls to enable or disable the use of cache disk. When disabled, recorded videos content will also be cached in the memory.
    • Management Portal displays on the server details page new graphs showing the usage metrics of the cache disk.
  • Hardened the ECDN server and fixed issues identified during the vulnerability scans.

  • We have now released our own content distribution solution that is dedicated for content delivery to the ECDN server instances. It includes set of “midgress” servers in select IBM Cloud data centers around the world. ECDN server instances will now connect to the midgress server in their region to get the video content. This eliminates the need for enterprises to open firewall rules to allow connectivity to 3rd party CDN providers.

    To see the benefits of these midgress servers, we will need to update the configuration settings on all existing ECDN server instances. In this update, the upstream server will be changed from the 3rd party CDN provider to the closest IBM midgress server.

    Once you give us an update maintenance window, we will trigger a batch update on all your server instances. It will take about 30 seconds to refresh the configuration for each instance.

  • ECDN Management portal will not have any downtime.
  • There may be gaps in the performance metrics for up to 15 minutes.
