Manchester issues with link

Sunday, May 6th, 2012

Dear Customers,

We are currently experiencing link issues between our two devices between Reynolds House and Telecity Williams Data Centres.

Our Network Team is investigating the root of the cause with our link provider and will update you as soon as possible.

Update

We identified a loop on our network which caused a port on our provider’s side to error disable. The loop has been eliminated and normal port activity is restored.

 

Maidenhead DC switch upgrade – 5th May 2012

Wednesday, May 2nd, 2012

Update 23: 48

The maintenance is now finished and and all tasks fully executed.

Should any customers experience any connectivity issues, please contact C4L Support Desk.

Thank you for your patience.

Dear C4L Customers,

You are receiving this email as notification of the following maintenance work that will be carried in Bluesquare – please note this is “Service Affecting” maintenance:

Start Date and Time: 19:00 05/05/2012

End Date and Time: 00:00 06/05/2012

The maintenance window is set for up to one hour but in the event of failure, a further 4 hours has been allocated to ensure normal service can be resumed.

Where:

Bluesquare, Maidenhead.

Description:

Network Switch Upgrade.

C4L as part of a phased approach to improving our service at Bluesquare will be replacing one of the switches servicing your connectivity.

C4L will be replacing the switch “Non” located BSQ3 floor 1, with a 10 Gb capable device. A 10 Gb fibre will then be disconnected from “Platini” on the ground floor of  Bluesquare 3 and reconnected to the new device. This will provide the starting point for a new 10Gb ring within the Bluesquare Datacentre. All customers directly connected to “Non” will be migrated to the new 10Gb capable device.

Additionally a 10Gb link between BSQ3 ground and BSQ3 floor 1 will be introduced.

During the insertion of the new switch and 10Gb links, customers not directed connected to “Non” will see traffic drop as layer 2 and layer 3 re-converges. There will also be some packet loss experienced when Vlans are migrated to the new 10Gb infrastructure.

During future planned maintenance windows, further 10Gb capable devices will be rolled out across the Bluesquare network to replace the existing legacy devices enabling C4L to complete the 10Gb ring.

Justification:

Certain customers within Bluesquare Maidenhead have been experiencing latency issues due to bottlenecks on the C4L network. As traffic flows have increased the latency issues and packet loss during peak times have reached unacceptable levels and need to be addressed as a priority. We wish restore the confidence with our customers in the C4L network and would ask that you bear with us whilst we implement this upgraded infrastructure.
