Outage last night?

[Simon]

Did anyone else have an outage last night from just before 1am?

I was a little more concerned than usual as I installed one of those mini UPS back up devices this afternoon, but it's not quite as simple as it might be.  I have a larger UPS upstairs in the lounge, so I could keep the router running during a power cut, but we actually did have a power cut the other night and although the router remained powered, I still lost the Internet. 

I later realised that this was because my internal box for the FTTP is downstairs, and obviously the power to that went out so I lost the connection to the router upstairs.  I therefore decided to buy this mini backup box that is supposed to power just a router or a modem, for the internal Fibre box downstairs:

It all seemed to be working fine, but now I'm wondering if I've done something to cause this Internet outage?  I've just been down and disconnected the back up box so the Fibre box is directly powered as it was, but my Internet is still down, so I'll just have to see what happens in the morning.

I'm back on this morning.  Looks like it came back just before 3am, according to my TBB BQM. 

But my latency has gone from about 5ms to nearly 20ms.  This actually coincided with me connecting the UPS backup box, and I assumed that was the reason for it (noise, perhaps?), but my latency is still up having disconnected the backup box.  What could be causing this and is it something to worry about?

I've now reconnected the UPS to the internal fiber box (ONT?), and as well as the latency still being higher than it was, I've now lost about 30Mbps off my speed (down from 108Mbps to 78Mbps on Speedtest.net). 

Should I just leave things to settle for a day or so, or is this UPS backup box looking like a bad idea?

Comments welcome!

I think you can disregard the outage, it's not uncommon for that time in the morning.

Assuming you dropped the line to connect the UPS at around 5.45pm yesterday it appears the resync has given you a degraded connection which is the opposite of what I would expect.

I have no idea why that would happen, perhaps it's something to do with routing

I've dropped the connection two or three times since then - to disconnect then reconnect the UPS box, and once to reboot the system.

So the latency has increased, but stayed the same since the first reconnection last night.

My speed has now reverted back to what it was, at 108Mbps, but the latency is still up on what it was yesterday.

Perhaps stop poking the bear and give it a chance to settle down?

I get this every now and then, I suspect it's Zen playing around with backhaul routing (FTTC here).

I don't do anything that's latency-sensitive so I just ignore it. After a while (anything from a few days to some weeks) it goes back to normal
