The coincidence is that’s not the only pipeline that’s been damaged by a surprisingly large anchor recently. Given that the pipeline routes are on the maritime charts and at least some of these have happened in places where you would not expect ships to be anchoring to avoid this sort of thing it doesn’t seem plausible to me that this is all accidental.
This is not pc-related though. Teletext was information pages transmitted on UK terrestrial (analogue) television channels in the long-distant past.
