I smell a rat.
Of course it could be a rat (probably fried)

I bet a lot of equipment cabinets are not designed to dissipate the
sort
of heatÂ* we currently have. I remember building simple circuits and
seeing how tolerant they were to both low and high temperatures as they
were to be in a field.

I wonder how often failures like this occur in India due to heat?

We do have hot summers and cold winters -- perhaps not to the same
degree and length, respectively, as India and Russia, but nonetheless we
are hit with weather extremes.

The annual temperature ranges in the UK are nowhere near as large as in
(say) Siberia or Chicago.Â* The UK has a maritime climate, which means a
relatively small variation from winter to summer.

That means it is not (normally) economical viable to 'design' for
extreme temperatures. We didn't used to point heaters or paint them
white! I don't know if I dare mention Climate (variation).

The extreme temperatures will produce faults in equipment designed for
such temperatures but still capable of operating quite satisfactorily
the rest of the time.
