GONG/TD fiber-optic connection

Monday morning, 28 July, about 8am local time, the fiber-optic cable to GONG at Teide was damaged.  An external company was called in. The repairs started later same day, and were competed next morning. GONG/TD is back on line, but the inspection indicated that the fiber-optic connectors are very old and not in a very good condition. The company is developing a plan for replacing these connectors with new standard ones. The date of this additional work is not yet determined. GONG/TD continued taking observations during this period, and no data were lost due to the incident.
