For headphones, DEFINITELY not true in my experience. There’s cheap and gimmicky (like Skullcandy), there’s perceived “luxury” brands like Beats (which aren’t actually worth their money) but then there’s brands that actually offer significantly better quality and longevity for the price, like Sennheiser, Beyerdynamic, Audio-Technica and Sony to name a few.

Seems like everything is back to normal, at least from what I can tell on my end and a lot of other users’ reports.

I do, a bit differently from what’s been mentioned here so far:

I actually host my server at home, running mailcow as my email-server-software of choice, and incoming emails do get delivered directly to my ISP-assigned IP via dynamically updated DNS records.

However: Outgoing email is delivered via an SMTP relay service, specifically Mailgun (I like them because for normal everyday email volume it’s free), because even when I was hosting the email server in a datacenter, it was impossible to not encounter deliverability issues.
