Engineers will be working in the datacentres between the 23rd of June and the 1st of July completing network upgrades. Plan of works:
Jun 17, 15:40pm GMT
23rd June - entire day --- Maintenance level - At risk --- Details - All DC's --- Pre-install checks and preparation work at the data centre racks
Jun 17, 15:37pm GMT
24th June - entire day --- Maintenance level - At risk -- Details - THN - DC -- Install new PDU's in the data centre racks --- Rack, Stack and configure 2 new core routers --- Cable up and configure new circuits from core routers ---
Jun 17, 15:36pm GMT
25th June - entire day --- Maintenance level - At risk --- Details - HEX - DC ---- Install new PDU's in the data centre racks -- Rack, Stack and configure 2 new core routers -- Cable up and configure new circuits from core routers -- Details - VOL - DC --- Rack, Stack and configure 2 new core routers -- Cable up and configure new circuits from core routers--
Jun 17, 15:35pm GMT
26th June - 12am -7am --- Maintenance level - Service affecting --- Details - THN - DC --- Migrate to new PDU's at Telehouse --- Core router and switch upgrades --- 5-10min outage at a time / per device being upgraded. Traffic might be affected while the traffic flow changes between core routers and switches
Jun 17, 15:33pm GMT
26th June - 8am - 4pm --- Maintenance level - At risk --- Details - THN - DC --- BGP NNI Migration to new service routers --- 10min outage at a time / per NNI session being migrated. Traffic might be affected while the traffic flow changes between the NNI and Internet failover
Jun 17, 15:32pm GMT
27th June - 12am -7am --- Maintenance level - Service affecting --- Details - HEX - DC --- Migrate to new PDU's at Equinix LD8 --- Core router and switch upgrades --- 5-10min outage at a time / per device being upgraded. Traffic might be affected while the traffic flow changes between core routers and switches
Jun 17, 15:31pm GMT
27th June - 8am - 5pm --- Maintenance level - At risk --- Details - LHC - DC decommission -- Decommission routers and switches - core devices will be moved to one of the other DC's --- Decommission servers - Servers will be moved to one of the other DC's --- The last remaining services will be migrated away from this DC, so this is an at risk change only
Jun 17, 15:25pm GMT
28th June - 2am -6am -- Maintenance level - Service affecting --- Details - VOL - DC -- Core router and switch upgrades --- Circuit migrations to new core routers --- 5-10min outage at a time / per device being upgraded. Traffic might be affected while the traffic flow changes between core routers and switches
Jun 17, 15:17pm GMT
29th June - 3am -7am -- Maintenance level - At risk -- Details - All data centres -- IPv6 maintenance --- IPv6 traffic might be affected while the traffic flow changes between the IPv6 sessions -- Circuit migrations to new core routers -- Traffic might be affected while the traffic flow changes between core routers onsite. Currently there is enough redundancy in place so this is an at risk change
Jun 11, 11:48am GMT
30th June 2021 - 3am - 7am -- Maintenance level - Service affecting -- Details - HEX- DC -- L2TP Maintenances to new routers - KCOM services only --- 5-10min outage at a time as new configurations are activated. Sessions should automatically reconnect and terminate after the new router changes.
Jun 11, 11:45am GMT
1st July 2021 - 3am -7am -- Maintenance level - At risk -- All data centres - Finalise all outstanding requirements for all DC's -- Traffic might be affected while the traffic flow changes between core routers onsite. Currently there is enough redundancy in place so this is an at risk change
