Is this satire? Ask it about June 4 1989, Taiwan independence, or Winnie the Pooh.

The testing VM is specified as VM.Standard.A1.Flex (Oracle Cloud)

Is this the endpoint you tested against? https://bgp.he.net/dns/t3.storage.dev#_ipinfo

Did you test from a VM in the same cloud that's hosting the product? If so I'm not sure "neutral cloud provider" is an honest statement.

I'd just be happy if organizations stopped doing business with software vendors that still mandate disabling DEP, ASLR, and the dreaded "Please disable your antivirus before installing".

I’m currently ~6 weeks into a billing issue with CloudFlare. They typically take 5-6 days to respond, ask you for verification to do things, wait another 5-6 days, then they ask you to do it because it turns out they don’t have permission. It’s a mess.

For comparison, this is roughly the cost of a pair of coherent 400G optics used in DWDM.

No escaping is done, so you can end up with a malformed profile if your SSID or PSK includes a < for instance.

iMessage is not about the color of the bubble. While the color is what's most noticeable to the end user, a non-iMessage chat means:

  1. Unable to rename group chats
  2. Photo sharing quality is lowered  
  3. Video sharing quality is abysmal
  4. Messages traverse carrier networks in plain-text
  5. Loss of undo send and delete
  6. Loss of inline replies
  7. Loss of typing indicators and read-receipts (if enabled)

Just to name a few.

I get Uncaught SyntaxError: Invalid or unexpected token

I'm guessing those quotes were supposed to be " rather than “ and ”.

Remember, Android doesn't only run on mobile phones and managed addresses are just one part of DHCPv6.

You seem to be completely ignoring the other aspects of DHCPv6. Your response comes off as extremely hostile towards others who may have different requirements than yours. Please consider that there could be other use cases beyond what you've been exposed to in the past.

> I don't even know what this means.

It means the Android operating system does not implement the DHCPv6 protocol.

> How is it impacting users?

Users of Android devices will be unable to obtain a managed IPv6 address configuration, other configuration, or request an IPv6 prefix (read: prefix, not address) via DHCPv6 Prefix Delegation.

> Are they crying out about it on support forums for the past several years?

For at least 10 years now[0].

Look closely at a lightning cable. The edge is metal. When you plug in a lightning cable, you briefly short every single pin together. There's probably a greater risk of bending a pin inside the port than there is shorting pins out.

Not only would CSP block it, but this type of behavior only strengthens Apple's decision to not allow third party rendering engines. Could you imagine the privacy nightmare that would ensue if Facebook could release a browser that bypassed any and all safeguards implemented by site operators?

There are a fair share of adults that do not understand height while driving either. Look no further than the 12'4" (previously 11'8") bridge on YouTube.
