it appear that our website can't be reached by BT.com customers, whitout any error message except "Can't reach this page" on the browser.
The weird thing is only BT.com customers have this issue, no one else in UK have it and our customers can workaround using another provider, but we have to fix that.
We have checked everything our side, but it seem to be a provide issue so...
Do you already have this kind of issue, is BT.com filtering something?
Thank you for your help!
