Painting times vary a lot

So i've been bothered by how long it takes for a pixel to be drawn even tho the maximum amount of time to wait is 30 seconds (according to pixelcanvas.io by the time of making this issue)

22:28:51 ->Load cached image 22:29:04 ->Websocket open 22:29:04 ->Waiting 54.889 seconds [++++++++++++++++++++++++++++++++++++++++++++++++++] 22:30:01 ->You painted white at [REDACTED] 22:30:01 ->Waiting 94.18 seconds 22:30:01 ->Somebody updated [REDACTED] with white [++++++++++++++++++++++++++++++++++++++++++++++++++] 22:31:37 ->You painted white at [REDACTED] 22:31:37 ->Waiting 93.31 seconds 22:31:37 ->Somebody updated [REDACTED] with white [++++++++++++++++++++++++++++++++++++++++++++++++++] 22:33:11 ->You painted white at [REDACTED] 22:33:11 ->Waiting 93.366 seconds 22:33:11 ->Somebody updated [REDACTED] with white [++++----------------------------------------------]

is this normal, is it a bug?
