+I want to really learn how to play and build this time, so my idea is to focus on a single class/build first and really study it. I think taking notes here will also be of great help.
+Example of things to note; 
+- skills working well together, or are just plain strong etc
+- cool passive skill tree notables
+- what certain stats on items do; which ones are best in which scenario

+It's nice to save uncut skill gems, in case a weapon drops that gives another sort of skill a massive buff.
+Example; i took all lightning stuff but now a staff drops that gives all FIRE spells +2 levels. Damn, if i'd had uncut gems, i could've swapped to fire.

+Vraag uitgezet bij Allan voor meer informatie.
+Allan: het komt al 1.5 maand voor; https://group-onecom.slack.com/archives/C02FT9KEFNH/p1729863978525299
+
+Uit dat bericht blijkt dat Jerry zou kijken of het Acronis is.
+
+Jeroen gecontacteerd om ff te vragen of ze dat al gedaan hebben; jeroen denkt dat het niet door Acronis komt omdat dat vooral read ops zijn en verspreid over de nacht.
+
+Allan stuurt graph met kantteking: "seems to involve alot of LUNs": `https://prometheus2.env.vps1-cph8.one.com/graph?g0.expr=count(lun_write_ops%20%3E%20(lun_write_ops%20offset%2020m%20%2B%20100))&g0.tab=0&g0.display_mode=lines&g0.show_exemplars=0&g0.range_input=30m&g0.end_input=2024-12-05%2005%3A47%3A35&g0.moment_input=2024-12-05%2005%3A47%3A35`

+Jeroen dacht mogelijk mysql dumps van shared, maar zou ook verspreid moeten zijn: ging kijken wanneer die gdraaid hadden, niks meer over gehoord.

+O.b.v LUN graph heb ik wat LUNs gepakt en bleek allemaal managed vps te zijn; Jeroen op onderzoek naar wat daar binnen rond die tijd gebeurd. Verdenkt PSA crons.
