Don't open the site unless you're doing so in order to sign. Use third party trackers if you want to check the number, the EU servers are struggling right now.
It won't give you any information right now as the API is down as well but that's the pace to check once the EU gets their servers up and running again
They haven't really gone down, they've just become very slow to respond.
Remember to keep going past 100k in case any signatures don't pass validation. Great job everyone
