There was mass 90k yesterday (between 4 and 5 PM GMT) on all EU/NA servers, and then there was noticeable lag at least till the time I logged out (9 PM GMT), so it could be related.

The following issues have been addressed according to Square-Enix in the thread:

[NA] FINAL FANTASY XIV: A Realm Reborn Hotfixes (Aug. 21, 2014)



An issue in “Crystal Tower: Syrcus Tower” wherein ground-targeting actions such as Shadow Flare used in the Golden Sacristy could also cause damage to monsters on the floor above.
An issue wherein, if a currently held weekly elite mark bill that was accepted during a previous week had the same target as the current week’s elite mark bill, and the elite mark was slain, then the current week’s elite mark bill, even if it is still unaccepted, is also counted as being completed.
An issue wherein the graphics for the NPC “A-Ruhn-Senna” did not display properly during cutscenes.

Does that answer your question?^_^

That would certainly explain why Amon was targeting the SMN.
