As per the various news reports there is a DNS Vulnerability affecting DrayTek routers. Over the past few days we have been auditing clients who have vulnerable models and a valid maintenance contract with ourselves. Work is already underway to patch devices in this instance however, we would advise all clients with Draytek hardware to check if there device is affected and update firmware as required:
Please see below 3rd party link for full details.
DNS Vulnerability Strikes Popular DrayTek Broadband ISP Routers
As a measure we will be blocking the DNS server used for the exploit on our network. However this could result is a loss of service should your device already be compromised. This unfortunately is a better option than using the compromised DNS server as detailed in the above news report.
If you have any questions please do not hesitate to contact us.
We are pleased to advise that we have recently added Telehouse North to our network location list and will begin enabling this for service over the next few months.
During this time we will be making changes to the current network located in Level3 Goswell Road in order to felicitate this. We hope to keep service disruption to a minimum and NOC notices will be published in advance of any works and the resulting impact they may have to your service.
Goswell Road as a result will be retired and all remaining services moved to our own in house data center. Details on this will follow as the THN migration is planned and the final build phase on our facility is completed.
Structured Communications will be implementing a change freeze from Monday 18/12/2017 at 01:00 GMT until Thursday 04/01/2018 at 09:00 GMT. This freeze is implemented every year during the busy Christmas period to ensure that no changes are made to our network or infrastructure which could affect services.
The freeze includes all changes to the network, non-essential maintenance, non-pre-planned change requests and infrastructure changes. Structured won’t be undertaking any planned maintenance during this time, unless we are responding to a fault.
Support tickets will not be affected by this change along with christmas changes to PBXs and current “inflight” orders already processing.
If you have any further questions regarding this freeze, please get in touch.
We are aware that 1 of our carriers has been rejecting outbound calls where the caller ID is withheld resulting in the call failing to setup where the call is routed via this carrier.
We are working with them as to why they are rejecting calls sent in this way. Until then and to ensure calls connect without issue with have assigned non-callable outbound numbers to each account that has an anonymous setup.
Calls returned to this number will be met with a non acceptance massage.
Following on from yesterdays issue with Google DNS reachability. We are advising all our customers who take our connectivity solutions to ensure they are using our DNS servers.
Clients with IPv6 are advised to contact us for further details.
Unfortunately issues with 3rd party DNS servers are not covered by our network SLA.
During the Christmas holiday period several of our suppliers will implement network freezes during which non-essential work will be restricted. They are as follows:

As per our NOC notice on the 02/10/2014 which can be found HERE. This is a final reminder to advice of these imminent changes. Any PBX / System that is not reconfigured to our EasyIPT service tonight will lose all inbound and outbound call routing once the existing 3rd party services are terminated.
All numbers will be automatically re-routed to the respective new trunks / accounts once the old services are terminated. In order to restore your services, PBXs will need to be reconfigured as above.
If you require your login information or have any questions, please don’t hesitate to contact us. Any users requiring out of hours assistance can be arranged FOC.
Structured Communications will not be held responsible for any loss of service due to none reconfiguration of PBX / Systems or configuration issues, not limited to incompatible products.
Following on from previous correspondence in respect to unmanaged SIP accounts we have seen the remaining unmanaged 3rd party PBXs connect to our new platform. As a result of this and in order to provide better levels of support we will only be providing accounts via our EasyIPT SIP solution from the 01/11/2014.
If you have not yet migrated over to your new trunk, then we request you do so by the 31/10/2014 to avoid any disruption in voice services.
Changes will be made to the number formatting of your PBX as the invite format has changed to canonical. Example: “442030000000” This number formatting can be added alongside existing PBX numbers to avoid anytime downtime. You will be able to instantly make outbound calls once your system is registered and once you are ready to swap over inbound calls, please contact support who will complete this for you.
If you are having trouble migrating your system or have any questions, please don’t hesitate to contact us directly.
In line with a previous NOC announcement whereby a BT IPX outage caused service disruption for our EasyIPT VoIP platform (both managed and unmanaged) Structured Communications have, as a result invested in a redundant carrier grade switch along with private bulk fibre and cross-connects to new and existing voice carriers. (known as upstream providers)
This solution enables us to directly peer with our upstream providers taking out the public internet and resulting in a more robust connection.
These new and existing providers directly terminate in to our carrier grade switch via private SST trunks and our private interconnects. This gives Structured Communications diverse routing in the event of an upstream network issue.
Customers who have a fully managed system with Structured Communications will be automatically migrated outside of hours.
Customers who simply take a SIP trunk from us via our existing carrier will be required to make changes to your PBX. (You will be contacted shortly via the email address on your account)
We are still awaiting the completion of various cross connects from their respective network providers and expect this to take no more than 2 weeks with the migration completed with 4 weeks.
If you have any questions then please don’t hesitate to contact us.
The 02 Wholesale network which is used to provide some of our ADSL services is being switched off on the 27th February 2014 following last year’s acquisition of the 02 and BE* retail customer base by Sky.
