DNS Resolver Work

We'll be making some changes on Wednesday regarding DNS servers. The work involves enabling a second set of customer facing DNS servers used by broadband customers.

This is meant not to be service affecting and customers should not notice the switch over.

At Risk - Maidenhead Routing, Thursday

We'll be doing some maintenance on our secondary BGP router in our Maidenhead datacentre (mainly used for email, customer hosting VoIP) on Thursday, probably around lunch time.

The work is to connect the router to a transit providers second network ring. This should not affect service though, but is considered at risk.

LNS upgrade, 31th Jan/1st Feb

We are looking to upgrade to new LNS s/w on the evening of 31st Jan or morning 1st Feb

Release notes from current issue:-

140: Fragmentation of existing fragments were wrong.
133: Average latency on graphs was sometimes wrong.
137/109/130/131: Several internal use changes.

This means we switch from B to A LNS, and graphs will show a gap. PPP will restart on the switch over.

The current LNS code has been stable for a long time now, and current s/w running on the B LNS since December. The new s/w has been tested on the test LNS and we expect no issues.

Mail Server Maintenance This Evening

We'll be doing some minor work on the POP3/IMAP servers this evening, the only disruption anticipated is when one of the servers is rebooted. This will affect some customers for a few minutes.

DNS server maintenance

There will be some maintenance work on our authoritative DNS servers on Friday the 22nd of January.

The work is not expected to cause any disruption, but it will be staggered so as to minimise risk.

Update: Work completed successfully.
