As I've said before vss 17-19 show this occurred after Christ made the sacrifice. He opened the temple in heaven as He is the temple.
Revelation 11:19 And the temple of God was opened in heaven, and there was seen in his temple the ark of his testament: and there were lightnings, and voices, and thunderings, and an earthquake, and great hail.
And what happened once it was open? and there were lightnings, and voices, and thunderings, and an earthquake, and great hail.
And you see great hail fitting with after Christ made the sacrifice?
Revelation 8:7 The first angel sounded, and there followed hail and fire mingled with blood, and they were cast upon the earth: and the third part of trees was burnt up, and all green grass was burnt up
Revelation 11:19 And the temple of God was opened in heaven, and there was seen in his temple the ark of his testament: and there were lightnings, and voices, and thunderings, and an earthquake, and great hail.
Revelation 16:21 And there fell upon men a great hail out of heaven, every stone about the weight of a talent: and men blasphemed God because of the plague of the hail; for the plague thereof was exceeding great.
These appear to be the only 3 verses in Revelation where hail is mentioned. It doesn't look like it's a pleasant experience, nor does it look like great hail even remotely fits with a time around Christ's sacrifice.
When I see someone this far off, such as you are here, I often ask myself, wonder what else this person might be wrong about? Don't some of you even read the details often included in verses? Revelation 11:19 doesn't just stop with the temple being opened in heaven, it goes on to say---and there were lightnings, and voices, and thunderings, and an earthquake, and great hail.
Below we see a temple open as well.
Revelation 15:5 And after that I looked, and, behold, the temple of the tabernacle of the testimony in heaven was opened:
And notice what follows. And it for sure has nothing to do with anything involving Christ's sacrifice in the first century.
Revelation 15:6 And the seven angels came out of the temple, having the seven plagues, clothed in pure and white linen, and having their breasts girded with golden girdles.
7 And one of the four beasts gave unto the seven angels seven golden vials full of the wrath of God, who liveth for ever and ever.
8 And the temple was filled with smoke from the glory of God, and from his power; and no man was able to enter into the temple, till the seven plagues of the seven angels were fulfilled.
Revelation 16:1 And I heard a great voice out of the temple saying to the seven angels, Go your ways, and pour out the vials of the wrath of God upon the earth.
2 And the first went, and poured out his vial upon the earth; and there fell a noisome and grievous sore upon the men which had the mark of the beast, and upon them which worshipped his image.
So I'm thinking maybe Revelation 11:19 is connected with the 7 last vials of wrath. We're obviously not on the same page here, that's for certain.
