End:       07-04-2017      05:59

Affected Services:

Network and Transit:

Brief interruption to service availability for the following services:

• xDSL services (inc ADSL, GEA-FTTC, GEA-FTTP)
• Dedicated Ethernet services (inc Ethernet, EFM, EoFTTX)
• Public Internet transit for Cloud and Hosted Services
• MPLS and PWAN Breakouts
• L2TP xDSL delivery
• PWAN Interconnect Services

Cloud & Hosted Services:

• Network access to virtual infrastructure may be momentarily impacted.
• Hosted Platforms (Exchange/Customer Portal/Web Hosting/Hosted Voice).
• Hosted servers may experience a reduction in peak disk IO available.

Service Impact:

Cloud & Hosted Services:

Periodic, momentary interruption for server access to the network.
Access to hosted services from outside of the Syscomm network may be periodically unavailable.
Virtual machines may experience increased I/O latency during the period as routine storage maintenance is undertaken.

Network and Transit:

Periodic interruption to networking routing.
Resilient services will reconnect as services are failed-over between routers.
Non-resilient services will experience brief losses of forwarding.
Private interconnects may exhibit a short period of disconnection as terminating equipment is power cycled.

xDSL Platform:

Periodic PPP drops as services are re-balanced on our LTS/LNS platforms.
Some circuits will experience brief periods of disconnection.

Outage Reason:

This window has been scheduled to extend our network reliability and deploy service improvements to ensure the long-term stability of customer systems and connections.

We will be conducting minor network & systems enhancements to support network growth and enacting maintenance routines to improve stability and provide additional capability.

It is anticipated that services will be typically available throughout this window, but users should plan for a risk of interruption to service during the maintenance.

Should customers continue to have issues beyond the completion of the maintenance window, please raise this to the attention of our support teams through your primary support channels (typically the Syscomm Portal).

Emergency Maintenance Notification – Power Maintenance HEX8/9 – 02/08/2016 – Update 1

syscomm 29/07/2016 0Comment

Update 29/07/16 17:11:
We have been advised the window has been extended to 00:00-03:00 with two potential impact windows during 00:00-01:00 and 02:00-03:00.

The following notification is to inform you of emergency planned maintenance which may affect your services.

Start:     02-08-2016          00:00
End:       02-08-2016         03:00

Affected Services:

Network and Transit:

Partial loss of service or interruption for a subset of the following services:

• ADSL & FTTC services
• Dedicated Ethernet services
• Public Internet transit for Cloud and Hosted Services
• MPLS and PWAN Breakouts
• PWAN Interconnect Services

Service Impact:

Network and Transit:

Minor interruption to transit as traffic is re-routed to other paths.
Resilient services will reconnect as services are failed-over between data-centres.
Non-resilient services will experience brief losses of forwarding.
Inter-DC traffic that may typically traverse via HEX8/9 will re-route over alternate paths.

xDSL Platform:

PPP drops on some services as they re-establish via alternative paths.

Outage Reason:

We have been advised that essential maintenance is required on UPS power feeds in Harbour Exchange 8&9 (Equinix LD8) following an unexpected power outage on the 20th of July.
These repairs are critical to ensure availability. The circuit breaker on the UPS feeds will be replaced and so work is being undertaken on an emergency basis.

Works will result in a loss of power to a large portion of the datacentre, resulting in a loss of service for some customers on our network who have services that terminate in HEX8/9.
The window for this work is two instances of an hour between 00:00 – 01:00 and 02:00-03:00, but the actual changes are expected to take a shorter amount of time within each window.

Should customers continue to have issues beyond the completion of the maintenance window, please raise this to the attention of our support teams through your primary support channels (typically the Syscomm Portal).
Please accept our apologies for any inconvenience caused, and thank you for your patience during these essential works.

Major BT Outage 21/07/16

syscomm 21/07/2016 0Comment

Update 16:16:
Most services should now be restored following repair work by power teams, restoring service to the affected suites.
Should you still be experiencing difficulties, please get in touch via standard support channels.

===

We are aware of of a major BT outage currently affecting some of our customers.

We have seen service drop simultaneously across multiple diversely routed BT fibre connections across London, and BT have acknowledged the fault and are working to restore services.

Our sincere apologies for the disruption this morning, and we will continue to provide updates as we receive them.
