Correction, this was a Denial-of-Service attack coming from the customer's server. (Not a DDoS coming into the server as previously stated.)

We've identified a Distributed Denial-of-Service attack coming into one our customer's Cloud Servers. This Cloud Server is running on head5, so any of you with Cloud Servers on that head may have been seeing a small amount of packet loss.

We've dealt with the situation and are in the process of contacting the customer. head5 network traffic should be back to normal!

We've been alerted to some intermittent packet loss for network traffic to our Manchester data centre.

You might be affected if you've noticed intermittent packet loss for a Cloud Server or Dedicated Server located in our Manchester data centre. This shouldn't affect anyone using services in York.

This is not necessarily related to status post #246. Tom's actions last week isolated the root cause of the problem and we've put mitigations in place.

On this occasion, we feel it might be a Distributed Denial-of-Service attack (DDoS) but we are still investigating.

Sorry about this! We're investigating and working to restore full service as soon as possible. We'll post updates here.

If you're experiencing any problems with your services at Bytemark that you think might be related, please do get in touch.

Expected resolution time updated: We are currently investigating.
