This network attack have been on for over Weeks now, sometimes the site goes offline automatically but other times it works fine, so just like we also suffers some cloudfire issue's with the forum' same is happening with talkimg lately, just try fine your way around the whole thing for now.
I almost forgot about it, but I've just remembered that, back in 2017-2018 when I started to write in this forum, DDoS attacks were very common, and sometimes the forum was down for hours or even days. Happily it is ages since I last suffered such a problem when accessing it.
I'm afraid that Talkimg is still down at the moment of writing these words, but I hope that it will be solved very soon and that, like with the past attacks to Bitcointalk, this will only be an anecdote in the near future.
