 Hi Vin,Just looked at the load on the server and it's very low indeed:  about 5.8% CPU and roughly 25% RAM memory.The SPGB site has heavy database use (MySQL) which I've also looked at.  The last 24 hours shows no slow database access.Internet Educational Section:Few Internet users are aware of how many potential areas a problem may occur in.  Am including this as general knowledge which, hopefully, will assist in deciding if I'm simply putting you off by saying 'all is good on our end' or if there could be a problem not under our control.The Internet is a vast array of independent individuals, hardware and software.  The intent is they work together.  Generally they do, but if one bit fails or is slow, it can cause a slowdown or complete failure.For example when using the SPGB website here's an overview of what needs to function in order for you to read the site and post messages:Under our control:Internet Server (the actual computer/s with associated hardware .. just like your computer at home.)Not under our control:- The connection from your computer via your ISP to the exchange where your ISP connects you to the Internet (including associated hardware and software)- All the 'hops' from request once your ISP sends it out over the Internet.  (Your ISP, generally, looses control after this point as well. (Again, of course, this includes all associated hardware and software with each hop from node to node.)Anyone can see the route their request to a website takes before it actually reaches the web server (web site).  The process is called a 'TraceRoute'.  Here's a traceroute from my computer at home to our server at worldsocialism.org:Hop    Hostname1    mark-desktop.local2    213.123.39.2253    213.123.38.254    213.123.38.375    213.123.38.136    213.121.204.337    81.134.231.2338    62.6.196.1059    core2-pos0-9-4-0.ealing.ukcore.bt.net10    peer2-xe3-2-1.telehouse.ukcore.bt.net11    t2c3-xe-2-1-1-0.uk-lon1.eu.bt.net12    213.248.82.24913    ldn-bb1-link.telia.net14    adm-bb3-link.telia.net15    adm-b3-link.telia.net16    hlm1-bfr1-as1299.tilaa.net17    ams1-bfr2-v1038.tilaa.net18    ams1-cr2-v1036.tilaa.net19    ams1-pod6-vc6-v1050.tilaa.netThe last hop is the WSM webserver.So anywhere along these 19 hops, there can be an error or downtime.  The Internet protocol will attempt to route around failures, but this can cause time-outs.So in answer to your question, after reviewing the last 24 hours data from our server I am unable to see anything that indicates a problem on our end.If you would like to run a traceroute from your computer (perhaps to verify this one part of the Internet), just do a search for 'traceroute'.Hope this was more helpful than confusing.  – Mark

Thanks Mark, I get the general gist of what you are saying.It is only when I click  to post my comment that things sometimes slow down.
