Date: Tuesday 9th March 00.01 – 04.00
Description: Maintenance to core network
Risk assessment: Loss of service to colocation and leased line customers

NewNet engineers will be carrying out essential maintenance on routers within the core network to upgrade the network for future expansion to fully enable IPv6 across all customer access routers. During this maintenance period engineers will be fully enabling IPv6 support across the whole customer access layer due to increased requests for IPv6 from customers.

Customers will see a loss of service for possibly up to 30 minutes while access routers are reconfigured. Services should be classed at risk for the whole maintenance period.

Reason for maintenance – Tuesday 26th January 2010

Window:         Tuesday 26th January 00.01 – 04.00
Description:    Maintenance to core network
Risk assessment:    No expected loss of service

NewNet engineers will be carrying out essential maintenance on routers within the core network to upgrade the network for future expansion.  During this maintenance period engineers will be increasing MTU values on routers to enable Jumbo Frames to pass through the network.

No customer facing outage will be expected, however, due to the nature of these works, customers should consider their services as “at risk” for the duration of the maintenance window.

NewNet engineers will be carrying out essential maintenance on one of our BGP route reflectors on Tuesday 12th of January 2010 00.01 - 04.00.

No customer facing outage will be expected, however, due to the nature of these works, customers should consider their services as “at risk” for the duration of the maintenance window.

The pipe rebalance will happen in an emergency slot at 6am GMT on the 29th December 2009.

BT IP-stream customers will loose their PPP sessions and may need to manually reconnect after this time.

RESOLVED: 11/12/2009 Peering sessions to LINX have now been re-enabled as issue has been resolved.

Due to some major problems on the main peering LAN (brocade) on the London Internet Exchange, NewNet (and some other providers) have temporarily disabled all sessions on that peering exchange on the affected LAN to prevent route flapping and blackholing.

All traffic will take alternate paths via other peering exchanges and transit providers, therefore no outage will be experienced by customers. However, certain routes may experience a slightly degraded service compared to their original path.

Please contact support.newnet.co.uk if you are experiencing any issues on your service.
