Possible LNS Issue 01/12/2016

We are seeing some oddness on one of our LNS routers which terminates some of our broadband circuits. We believe this is only affecting our management access and not the service provided over this.

We are working with the vendor to understand this and hopefully resolve this. Assuming this is not customer affecting we may need to reboot this LNS later this evening causing a brief network blip as the sessions re-connect.

IF we find this is affecting service earlier we may have to perform the reboot earlier. We will update this as we know more

 

Outage thn-gw2 22/11/2016 [resolved]

Our monitoring started reporting that one of our core routers in Telehouse (thn-gw2) failed just after 19:15 this evening. We have now rebooted this and the router appears to be back and stable. We will investigate the cause of this and update the ticket as needed.

Most customers would not have noticed this (other than some slightly different routing) and possibly a few short periods of packet loss as routes re-converged. A small number of connections are directly connected and may have seen a longer outage as the router was restored.

We believe full service is now resumed – If you are seeing any ongoing issue please contact support in the normal way

We are sorry for any issues caused by this

Telehouse Maintenance 9/10/2016

We are receiving alerts from our UPS in Telehouse. We have therefore scheduled a maintenance to visit the site and either replace the batteries on the UPS or replace the UPS as needed. Depending on the situation there may be an outage for Telehouse North based services late this evening for upto 90 minutes although we will of course keen this to an absolute minimum.

NOTE this UPS is in addition to the building UPS and Generator.

This work will affect most broadband services and some Leased lines.

We are sorry for the short notice but want to resolve the possibility of an issue as quickly as possible and at a time when least people are using the service

We will update this post as the work progresses

Now’s the time to migrate to Merula to stop a broadband meltdown

On Tuesday 13th September, Apple releases the new version of iOS v10 following the launch of their new iPhone 7, followed not long afterwards by macOS Sierra, the new version of their desktop operating system, on 20th September.

We expect there to be a significant up-tick in traffic because of this, both through the whole day and probably well into the following ones.

We have plenty of spare capacity within our network and don’t envisage any problems directly affecting circuits supplied by us but the nationwide backhaul providers will be under some pressure, so be aware that transit may be slower than usual until this traffic dies down naturally.

There is still time to move to one of our fantastic unlimited tariffs before this onslaught hits!

If you’d like to upgrade we can offer you a FREE migrate from ADSL or another FTTC supplier so please get in touch straight away.

Manchester Network Upgrade 14/08 – 15/08

During the afternoon / evening of the 14th August we will be performing a range of upgrades at our Manchester PoP. These include

  • Replacement of UPS  Batteries
  • Upgrade Core Switches
  • New Access Switches
  • Upgraded Core Routers
  • New Servers

During some periods of the maintenance routes that would normally route via Manchester will take an alternative route. It also means that some backup leased Lines will be unavailable for a short period.

While the maintenance window is wide we hope that the actual core network will not be affected for more than an hour or so – hopefully less. All the replacement hardware has been setup and tested in our Lab. Note that we are not anticipating any issues with our core network in any other location and Broadband, etc should be affected – However it should be considered ‘at risk’. These upgrades should further enhance the stability of our core network

If there are any questions please raise them via the support mailbox

Issue with post.merula.net

Our primary outgoing smart mail server was down for a short while from approx 2pm due to a customers PC becoming compromised and sending a very high level of spam. We paused delivery on this server while the affected emails where removed from the mail queue to minimise the risk of the sever being black listed.

Mail delivery has now been re-enabled. While clearing the mail queue there is a small possibility that email sent just before the incident may not have been sent. If you are awaiting a reply to an email and are not sure it is probably safer to re-send just in case the email was not received.

We are sorry for the slow updated but we where concentrating on resolving this issue and did not anticipate the mail queue clearing to take so long

If you are still seeing any issues please drop an email to support as normal or call us on 0845 330 0666
