Nowadays, this type of connection problems is on the rise for me.
Strange enough. This applies for both local and international links.
Where are the good old days of internet freedom?

It's just a temporily problem with the provider. But I will submit olithink soon to softpedia, so there will be a second source.

5.1.2 is apparently much stronger than 5.1.1, but 5.1.1 is much more successfull against Glaurung.
Could be an explanation that 5.1.2 has pv-search (like Glaurung) and 5.1.1 has not (like Crafty)?

I'll start testing with 5.1.2 tonight, as soon as
my scheduled tests are complete.

Your tests show a ratings increase around
50-70 points.

Best,
