 From a terrestrial perspective, the recent solar flare activity would

inductive (copper) loops that collect those pesky electron charges. 
In North America, I imagine that this is mostly local loop issues, 
since the majority (everything?) that is of any appreciable distance 
is fiber.  It is perhaps the case that the Canadians and Alaskans may 
see more of an issue even on their short local loops, since the more 
polar segments of the Earth bear the brunt of the storms (if I recall 
my astronomy courses correctly.)

Its probably not statistically significant, but the hit on power
supplies after the recent solar flare did catch my eye.  I don't
recall a similar rise occuring in the past.

But I can't compare the number of power supply problems to the
same period last year because ATIS Network Reliability Steering
Committee has removed all of its public reports from its free
portion of the web site, and I don't really want to spend $50
to buy a copy.
