This is likely to relate to something that I've mentioned in another thread today. Our GEA Fibre services are provisioned on a 'Standard' DLM profile rather than the less aggressive 'Speed' profile.
You can see you're on GEA Fibre by logging in to your Customer Portal and clicking "View Line Data" towards the bottom right of the My Services Home page. In the Broadband Line Data section it will state "Your current line technology is" followed by the detail.
While on the previous platform you'll have been on the 'Speed' profile. If the increase in latency is an issue for you then we could modify the profile back to 'Speed'. The trade-off though is that you may experience more errors or disconnections as the 'Speed' profile allows more frequent errors and up to re-syncs within a 24 hour period. If you didn't have issues prior to May (when the switch occurred) then I doubt you'd have any new problems if we changed it for you now.
Drop me a PM if you are interested in changing the profile please.
