There seems to have been a some power issues over at Telehouse North this afternoon. A few ISPs and hosting providers are reporting outages and most notably LINX have suffered a significant drop in traffic. This, however, was due to a port upgrade for a customer – and not caused by the power failure.
LINX provide an open peering relationship with most companies within the industry to allow traffic sharing and hence reduce costs. This is done by having fixed cost for the connections so what you find is LINX ends up shifting huge amounts of internet traffic. At its peak today they supported nearly 600 Gb/s.
We don’t currently use LINX and purely rely on transit however with a good mixture I don’t see why there should have been such a big impact but obviously a lot of ISPs rely THN!
