This work forms the final phase of network upgrades that have been undertaken recently to increase core capacity and allow for new L2TP services.
During this window we will be moving the final interconnects to there new respective cores as well as undertaking a complete rebuild of the legacy core in order to transition this to an Access device. Configuration for the interconnect migrations will be in place prior to the physical moves, however there will be disruption expected on the following peers due to routing table updates following on from the disconnections / re-connections which is expected to be around 30-60 seconds per event.
Adapt / Level3
MDMX / Easynet
There will also be some changes made to our internal BGP sessions and filters due to the nature of the above works which will also result in disruption while tables are updated and BGP sessions established.
Once the above interconnects have been moved and tested, we will then be undertaking the rebuild to Access01. Unfortunately this work will result in several reboots of the device as well as some major configuration changes. This will require a longer downtime, however will be towards the end of the maintenance window.
The above works will affect all direct services (EasyIPT, EasyHTTP, EasyBond, EasyEFM, EasyLL) We apologize for any inconvenience this may cause.
UPDATE 01 – 23:30
Works have been completed with all the interconnects moved from the now “ACCESS01” device to there expected core devices. During the migration and build of our internal BGP sessions we did see an extended outage due to configuration. This was resolved within 45 minutes. We apologize for the unexpected extended disruption.
Due to limited remaining time and further planned disruption expected with the full rebuild of Access01 the decision was made to suspend that part of work and the device would be reviewed remotely to see if these changes could be done another way.
A full review will also be under taken over the next few days to confirm the changes made and any amendments required due to the unexpected configuration issues seen.
