Hello Stian
Thanks for your answer, and the nice words about our site.
I did try to run Curl. I understood, from the description, that it is included in Windows, but it did not return anything, and I’am not normally working in that field. And I was unsure which version, I should use. So I dropped it.
We have at least 2 sites making troubles, an maybee a few others:
https://davidharvey.org – I think we have around 2 links, it is pretty easy to work around.
https://solidaritet.dk – It is at very central portal in Denmark, and we link to a lot of posts.
They both a status in Dead Link Checker saying “Timeout”
We are in contact with the people working on Solidaritet, so if we knew what they should change in their system it would be nice.
