[Cryptography] Is this a "relevant" attack against HMAC-MD5?

[Ryan Carboni]

That 2^72 attack against MAC MD5 is an online attack.

It is only in the reach of the NSA if it's a server capable of handling
2^72 queries per year.
Keep in mind if each query was one byte, that would be several zettabytes
of data.

The internet isn't even that big.
