Simbrief seems to be down, I can’t access the website, nor the status page, and it’s been like so for the past hour.
All systems are go, according to our monitors.
It sounds like it might be an issue with your ISP, unfortunately.
Try rebooting both your computer and your network router to see if it makes a difference.
Tried everything, still not working. It also won’t let me import any Simbrief FPL into any aircraft, so I guess it’s still the servers 
Tried again every possible fix from this planet, it does not work. Contacted my ISP, they said they can’t do absolutely anything about it, and it’s rather a problem from Simbrief and prompted to ask you about any IP Bans, or down servers or errors
Hi,
Can you try to open simbrief.com on your mobile phone? What do you see …
Also, can you run the following command in a CMD window:
tracert simbrief.com
Please post your output.
Thank you
Richard
Resolved by itself, apparently, thanks 
Thanks for the feedback… Normally, we inform our users here on the forum when a service is down or unreachable.
Anyway, good that it is solved now
Cheers
Richard
