@ike it sure is! and i'm relieved. (i can see that 1.1.1.3 now resolves my domain. yay!)

i did fix the hole by which people were able to post unauthorized notes at notes.interfluidity.com. but the notes i found there were maybe a bit spammy, but not malware or nsfw. i still don't understand why i would have been blocked.

thanks again for letting me know about this, and figuring out who and how i was being blocked!
