We have identified that Ethernet customers are not seeing archived graphs for last few days and the cause is part of the recent router upgrade code. We plan to carry out a further upgrade this evening which should have little or no disruption, and should rectify this issue.
There may be a blip on some TalkTalk lines during this upgrade.
Work completed for now - seems to have gone as planned. There was a small TalkTalk line blip as expected.
