It's an interesting theory, that temperature affects overall throughput.
Their assumptions on other conditions that affect bandwidth
consumption are off IMHO. Our own data directly refutes

I'm not sure the effects are so big compared to the actual speed that
they are noticable for the average user. We also don't have any proper
data available but

I read the article and the follow up posts and I wonder if we are all
using the same definition for speed here. The article seems to
imply you don't get 6 Mbps on your DSL line in summer because the
copper is hotter and it's harder to push electrons down the link.
That is clearly BS,

It used to be that we would notice this, except that it had everything to
do with temperature *and* dampness. In the '90's, it was still quite
common for a lot of older outside plant to be really only voice grade

Trying to pinpoint the failure point on one of those circuits is a PITA as

it rains is an exercise that Sisyphus would probably decline.

I was in ASA class just last week and asked about this exact issue.
I was told that at this time you cannot do the IPSec VPN in Multiple context

software issue that Cisco is working on and has in test at this time. No
