Last night, my blog suddenly became inaccessible. After checking the reason, it turned out that Blogger's custom domain function was blocked again, and ghs.google.com could not be pinged. As a result, the two blogs I have on Blogger were both inaccessible. Last night, I spent a lot of time searching online for available backup IPs for Blogger but still couldn't find one. Finally, this morning, I managed to find a usable IP and quickly switched to it. Ha-ha~ It works now, everything is back to normal!
