Some of the traceroutes are going a bit weird, e.g.:
[tt]traceroute -q 1 -N 1 -T -p 80 212.159.8.110
traceroute to 212.159.8.110 (212.159.8.110), 30 hops max, 52 byte packets

Perhaps some routing is messed up, or there are some routing changes that haven't fully propagated to all bits of network kit yet?
Edit: Whatever the problem was, it seems to have cleared now and it's working again.

Whilst one may connect to either of the IP addresses on different occasions that one connects to the forum, which I've noted when I occasionally check, on re-reading your post today I was minded to check the traceroutes with the above results.
I further checked the consistency of those traceroutes with which ever IP I was actually connected to on the Forum. But because I was monitoring the Forum IP more closely I then observe that despite always having at least one tab open, the IP address had changed after either I posted or refreshed a tab, so I now need to monitor more closely to see exactly when it does change.
However before I do that, I'm going to set the IP address in Hosts to see if I get problems with one IP address and not the other.

Things are much more troublesome of 212.159.8.110 but still testing.

Quote from: Anotherone The problem is they should not be different which is why I would not call them "usual"
The gateways are in buildings in different parts of London and there's routing from each back to Sheffield with a link between the two London buildings - of course there's a high chance that the routing may be different!
Edit: Too add to that the targets are in different datacentres, one is in peh and one in ptp.

And actually I didn't mean why are they different in that sense, why the different number of hops?

Looking at the trace routes the first goes pcl -> ptw -> ptn -> peh.
The second goes pcl -> ptp so of course it has fewer hops.
I'm on a ptw gateway and you can see the routing for me goes the other way:

If you gateway hop on to a ptn gateway you'd see something different again.

Having said that, I'm not convinced that this doesn't have a bearing on some of the issues being seen - if you follow all the negatives!
I can do traceroutes to each of the ntp servers and they are all the same number of hops. They are in different data centres. How does that come about?

All four IPs are definitely present in both ptw and pcl - you'll see the traceroute doesn't leave ptn/ptw or pcl depending upon where you are connected.

That would seem to trace to only the pcl ones. I guess on a ptn or ptw it will be different then. I'll have to try hopping and check it out again - a while since I have. But on pcl-ag03 it's working well so reluctant to hop atm.
In terms of problems - this "Connection Problems. Sorry SMF was unable to connect to the database.........."
has come up several times now whilst on 212.159.8.110 but I didn't get it once whilst on 212.159.9.110.
