My tower came out of reinforcement around 1am AU last night. I logged in just after down time and tried to online some extra modules and empty other POS modules so the loss wouldn't be too much.
I'd spoken to a couple of people during the day from other alliances/corporations in the region and said that there might be capital ships in my system around the time that the tower came out of reinforcement. I said I wasn't asking for help, I'd resigned myself to losing the tower, but capital kills are capital kills.
I don't know if anyone did send a scout through but I provided the information in good faith because it was very probable that capital ships would turn up to finish the tower off.
The Morning After
I went to bed in the belief the tower was lost and we'd have new occupants in our system. I'd decided I would be as annoying as possible by attacking any towers periodically and, if I could, reinforce any tower when I could.
So I woke up, checked EVE mon and was a little confused to see no notifications or mail overnight about the situation. I fired up my industry tool and checked my towers.
There it was, no longer indicating it was reinforced and the stront had been replenishe (probably by my CEO).
I've started production again, losing near 2 days has sent a few of my other towers off whack and its a little annoying but I think I'll stop production for two days in those to allow this one to catch up. I have plenty of materials on hand for sale and it really doesn't impact my industry.
I'm still not sure WHY my tower was reinforced but I'll be bringing in new POS defences and ammunition next JF run. If I can anchor dozens of guns in preparation for a repeat I may be able to piss them off enough that they'll reconsider any attack. A small chance but it worked for a recent POS assault I was going to be involved in.
I'm sure there are more things I can do and I'll be speaking to other experts, people with experience in POS Sieging and Defence, and my Alliance CEO to see what we can do to protect ourselves in future (as I pay taxes to the alliance for running the towers).
