Other websites are opening fine so it is not an internet issue at my end.
Each country has different internet lines, both provinces, regions and can also be caused by weather, clouds, rain etc.
Overall for today the Btt Forum still looks normal as usual, try checking the internet tower you are using, may have collapsed or is being repaired and also the electricity in your residence may again run out of oil.
We are here for now, opening forums are still like airplanes in the sky.
