Good afternoon,
Today I need your help, regarding our website who's not reachable from our customers using Plusnet as ISP (pro version).
They can resolve the name but can't reach the site (web page can't be reached).
They tried to ask support about this case, who told them that was related to a lack of DNSSEC but many sites don't use it so we can't be the only one blocked...
We went deeper and see that the SYN paquet comes well from our customers to our server, but they never receive our SYN ACK packet, so the TCP handshake fails. Our traceroute and other investigations show that packets are stopped at their kingston server and wouldnt go any further.
If you have the chance to try, please let me know if you can't reach the landing page: https://uk.symbility.net
Thank you for your help!
Fixed! Go to the fix.

I'm not using PN network, but one that also uses BT infrastructure.

Sadly that doesn't seem to connect via the PN network either.
Superusers are not staff, but they do have a direct line of communication into the business in order to raise issues, concerns and feedback from the community.

It's due to the issue described here.
jira.innovation-hosting.com and uk.symbility.net both resolve to IP's in the same subnet.

Hi @bobpullen, so if I well understood, this is related to a routing issue that is already under investigation PN side.
Do you have an ETA for this ticket?
Also, I saw the reference INFOPS-3100 but where could I check is followup as we aren't PN customer?
That being said, thank you very much for your help.

Yes, it's under investigation.
I've asked for somebody to give me a nudge once some progress has been made so will pop back here once things have been sorted.
Can't provide an ETA though I'm afraid as we're dependent on third parties.
