I've found access to surreyramblers.org.uk quite slow for the last few weeks, but it's got worse. Here are some timings from just now:
Backend
Login - 50s
Open Article Manager - 36s
Open Article - 30s

Frontend
Open homepage - 28s
Visit walks page - 11s

My broadband seems OK - speedtest reports 37Mbps down and 9Mbps up.

Another user has reported extreme slowness in accessing the site as well.

Is there a general server problem or is it just this site that is affected?

Thanks,

David
