I think on 1/1, they rolled out a new sign-in page, it was very glitchy at the beginning but it's gotten better since.

I have T-Mo, so I was getting SMS in addition to messenger services. Messenger messages are not as reliable as SMS. I had an argument with my gf via SMS over the pacific ocean for 3 hours, because i forgot to tell her I went on a biz trip The SMS was so reliable, she thought I was lying and that I was on the ground avoiding her
