are you able to access freepascal wiki at wiki.freepascal.org ?
I can access them however, at times I have DNS lookup failures with curtain URLS where I'll get a report the link does not exist but if I keep retrying up to lets say 5 times then the DNS finds the site address. once found I have access to it for a while but If I don't keep at it, I'll have to go through that again.
It seems like there’s an ongoing “cyber war”. Tough luck if you’re caught up in the middle.
