Question:

when Blanchot says that the disaster is the “limit” of writing but not “beyond the pale” of writing (7),
what do we take beyond the pale to mean?

Literal:
1. A stake or pointed stick; a picket.
2. A fence enclosing an area.
3. The area enclosed by a fence or boundary.

 
Also:

Pale (geography): a space or jurisdiction lying within a clear boundary.
  –e.g. British rule over French and Irish Pales (13th-16th centuries)

Pale (heraldry): a vertical mark running down the center of a flag or shield.

Idiom: beyond the pale: “Irrevocably unacceptable or unreasonable”
  –Phrase Origin

 
So, the disaster is outside experience, but “within the realm” of writing (expression) — perhaps an expression of this “outside”…

Result?

“The Semperoper, the Dresden state opera house, in 2007. It was destroyed during the bombing, but was rebuilt in 1985. It opened exactly 40 years later on 13 February with the same opera that was last performed before its destruction, Der Freischütz by Carl Maria von Weber.”
