There is a routing problem affecting access to some of our services, eg our website and L2TP service among others. We're investigating.
This looks to be related to one of our IP blocks that we use for some of our services, we're investigating still.
Routing restored at around 17:48
Initial investigations show that this looks to be due to one of our upstream transit providers not routing traffic to us for one of our IP blocks. The short term fix was to enable the block on some of our other transit provider's links. - we're still investigating further.
We're still seeing some places on the internet routing some IPv6 traffic incorrectly, this is still being investigated.
This was caused by a third party internet provider, with whom we have been in talks with about them providing us some transit and had provisionally configured some of their routers to allow us to announce our IP blocks through them. We had not got to the point of actually setting up the service though. However, one of their routers malfunctioned and got in a state where it was re-announcing our IP blocks to some of the internet which meant some of the internet was sending traffic bound for us to them. We mitigated some of the problems by announcing more specific routes and also got in touch with the provider who promptly fixed their router.
