For a brief period, the RADIUS server here in Huntingdon that authenticates ADSL logins was refusing connections. This is now resolved and any ADSL circuits that weren’t able to login should have automatically come back on line again. If you are still seeing issues, please re-start your router.
28th July: the Windows 10 code is currently being downloaded “in the background” to machines that have pre-ordered the update which means that some back-haul providers are already seeing some slow-downs. Be aware that this is likely to continue for a while.
——————-
Microsoft are making available from this date their new version of Windows. It will roll out over a period of time, starting on this date.
Whilst we will have brought on-stream additional back-haul being provided by our suppliers, we believe that there will still be some instances of higher latency and slower speeds caused by this, that could affect many of our users especially as this may also affect our supplier core networks.
We will make every effort to mitigate these effects but you should be aware this may be an issue before raising a fault ticket.
Change of date:
We’ve been advised by Cogent Network, one of our transit suppliers of work to be undertaken on some of their core routers. This should not mean any loss of service to us or our end-users as we have multiple diverse routes into and out of our data centres — there may be a few moments of route instability until they re-converge and stabilise.
Maintenance window:
Date of work: 8.8.2015
Start time: 00:00 BST
End time: 02:30 BST
Place of work: London Telehouse North
Work description: Hardware upgrade on Core router controller cards
We just saw a temporary blip on one of our interconnects which may have caused a brief < 1 minute loss of connectivity to some services hosted here in the Huntingdon data centre.
This appears to be a momentary issue only but we are investigating the root cause.
Two of our supplier transit links are receiving software updates between 1am and 7am. There should be no down-time and minimal effects other than a few transient routing issues whilst traffic re-converges.
We are seeing an issue with one of our Telehouse Gateway Routers. To resolve this we will need to reboot this later this evening to resolve the problem we are seeing
This should not cause an outage but may cause a routing blip as the routes transiting the router re-converge. We hope the router will not be down for more than 30 minutes – although we will will be monitoring this and will update here as needed.
If you have a domestic-grade router you should check by reference to this report, whether or not it may be affected by a recently notified vulnerability https://www.sec-consult.com/fxdata/seccons/prod/temedia/advisories_txt/20150519-0_KCodes_NetUSB_Kernel_Stack_Buffer_Overflow_v10.txt
If you believe this may be the case you should contact the manufacturer direct or check their web-site to see if your model has been patched and proceed accordingly.
Due to a memory leak one of our core routers (thn-gw2) has just rebooted. We are seeing all services back as they should be.
As this is one of a resilient pair of routers there should not have been any outage – BUT there may have been a brief ‘blip’ while the network switched over top the backup router (and another when thn-gw2 returned to service).
We are monitoring the issue and will update this post if we see any further issues
UPDATE:
Through investigations Level3 isolated the trouble to overutilization on a link from Toronto to Chicago. Traffic was rerouted to avoid the trouble and services are now restored. Level3 will continue monitoring services to ensure continued stability.
Please be advised that one of our transit providers, Level3, are experiencing an issue that may result in packet loss to some destinations. We will keep you updated as and when we receive more information. If necessary, we will disable this link until they resolve the problem
