There was an issue involving BT ADSL connections between approx 1:30am and 3:40am this morning [11/03/2012].
Working with BT we now believe these issues are resolved and can see most connections back on line.
If you are still seeing an issue please reboot your router and if this still continues please call or email support in the normal way.
We are sorry for any problems this may have caused
One of our shared hosting web servers (cgi.merula.net / 217.146.105.1) had some issues earlier today due to a attack against a number of scripts on the server.
We believe that the attack has now been blocked and the issue resolved.
We are sorry for any issues this may have caused
Or primary outgoing smtp server crashed earlier today due to a memory leak.
The server was rebooted which restored service. We are investigating the root cause to see if we can prevent this issue re-occurring.
We are sorry for any issues caused
To resolve a bug on our ADSL gateway routers we will be performing a firmware upgrade this evening at approximately 10pm. This will cause approx 50% of ADSL sessions to us to drop for 5-10 seconds.
Most sessions should automatically re-connect, however if your session does not re-connect a router reboot should re-connect fine.
If there are any issues please email or call support via the normal methods
This work is now completed
At approx 3:30pm today there was a power outage from the raw mains to our Huntingdon Data Centre which resulted in the loss of a single phase of the mains feed.
While we have a UPS and Generator backup to the data centre the actual failure coincided with a surge from the data we have here – this lead to our UPS protecting itself and our servers and consequently taking down the power feed to all servers in the data centre.
As soon as we were sure of the cause we manually transferred the power feed to our generator and restored power to all affected routers and servers – most were restored within 20-30 minutes. We are currently going through all remaining servers and checking their status.
We now believe that the main issue has been resolved and all public facing services and co-location servers are back and accessible.
IF you are still seeing an issue please call or email support the normal way and we will investigate and resolve the problem.
We are sorry for any issues that have been caused by this outage
app approx 5am this morning our main outbound email server crashed do to a memory issue.
This has been resolved and all services should have been running again just after 8:30am
We are sorry of this issue affected you in any way
Some of our users may have noticed some periods of packet loss and inability to reach certain locations today.
We have been working on this issue since the early hours of this morning – and after a lot of debugging e have traced this issue to a change made by a supplier to two of our inter-site fibre links.
We are liaising with the supplier to get this fixed and have made some temporary changes to stop the issue re-occurring however this had left the network with less automatic resilience than normal.
There is a small risk of a network break on our other services causing some areas of our network to become unreachable – however if this happens we will manually switch over to the backup links. In addition once or supplier completes work here there will be an at risk period when we swap back to all current links.
Virgin Media have now replaced a faulty NTE in our Huntingdon Data Centre which appears to have now resolved this issue. All of our links and resilient paths are now fully enabled. We will be monitoring this issue t ensure it does not re-occur.
We are sorry for any issues caused by this problem
Due to an issue with our router in Sovereign house we are performing a update earlier than planned.
This will limit access to servers on the 217.146.105 and 85.158.153 IP ranges.
We anticipate the downtime will not be longer than 90 minutes and will start approx 8pm this evening.
Note this will NOT affect access to ADSL and connectivity services only a small number of servers (including the merula website and portal) that are on the IPs above.
This work was completed though took a little longer than planned. All services were restored just after midnight
Our suppliers will be carrying out planned maintenance on one of our UPS systems at our Huntingdon Data Centre during the afternoon of the 1st October 2012.
While there should be no impact from this there is always a small risk with any work.
We will update this post on completion of the work
We are aware that some u8sers on BT based Broadband packages may be seeing slower than normal speeds at times. This is due to a combination of higher than normal usage (we are assuming this is related to the Olympics) and BT capacity issues in London. We are chasing BT for a resolution to this and working our hardest to ensure that we are able to provide the best speed possible.
Please note that our leased lines and o2 and cable and wireless connections are not affected in any way.
We apologise for any issues caused and are working with BT to resolve this as soon as possible.
