Goodness Gracious! This sounds a bit tasty.
Like the previous postee I'm wondering why the problem would be North Sea specific. As NERC uses MultiRadarTracking I would have thought the problem could manifest itself anywhere.
Anyhow, it sounds like the management have done the right thing in reducing the TSFs for the affected sector in concert with the issuance of the instruction. From a customer service angle this is quite a brave step given the huge delays North Sea sector tends to generate! Maybe this is a sign that the old ways are on the way out and the new incumbents are on the same side as the workforce. Or did SRG insist on the TSF reduction?
