Sorry for the delay…
I have been informed that:
“ The change has been fully deployed.
“ Our expectation is they should not see 5.4.0 anymore.
“ However, they might see a few ‘5.5.4 Transaction Failed’ error …
How is it going now?
5.4.0 and 5.5.4 … are we seeing a lot less / none?
Otherwise, Happy Monday! (or something) :)
Aloha,
Michael.

We saw this in small part today, starting at 10:45 am (Central), and clearing
up by 6:36 pm. Our email server logged this;
399 TCP Read failed (Connection reset by peer after 32 seconds)
Across several MXes.

Subject: [mailop] Hotmail connection errors
Hello,
For about the last hour we have seen a huge spike in connection errors and
timeouts at Hotmail MXs. They are holding connections open for a long time and
then simply timing out. Spread across entire netblock.
Anyone else seeing similar?
Tara Natanson
