Sorry, Roly and Sarge - Plenty of 503s and 504s :(

respond on threads is only available to members, it is password protected, they can't load that page

I was pinging the front page, and loading response on threads in another tab, the idea being that pinging the front page may not tell you much about load time of other pages.

i don't have much time - got company - but using pingdom to check dns servers indicates some problems

Pingdom Tools

warnings were given here:

Delegation

Superfluous name server listed at parent: ns4.e-cigarette-forum.com

A name server listed at the parent, but not at the child, was found. This is most likely an administrative error. You should update the parent to match the name servers at the child as soon as possible.

Too few name servers (1).

Only one name server was found for the zone. You should always have at least two name servers for a zone to be able to handle transient connectivity problems.
Nameserver
ns1.e-cigarette-forum.com.



Could not find reverse address for 72.52.242.207 (207.242.52.72.in-addr.arpa.).

PTR record(s) for the address could not be found in the .arpa-zone. (ip6.arpa. for IPv6 addresses and in-addr.arpa. for IPv4).

Wow!!!!!!!!!!Does anyone know if this could be causing our problems??

 

[SilverBear]

The red line below is the time it took for me to navigate from iGoogle to ECF, to Outside, into Response on Threads and then do a refresh. About 33 seconds. That was with a relatively fast reload time... which has not been the case recently.

I'll do a few more tests as the day goes on.

[rolygate]

@Whiskey
No it isn't. We have two functioning nameservers (and one with a DNS issue which is not relevant). A new server was added yesterday which is still being set up.

 

[CES]

A third server? Yay!!!!

 

[rolygate]

That brings the total to four on ECF.

I'd like to create a map of where slow service is being received to see if there are some specific areas, then we could figure out how to provide a CDN service there. We tried one provider but it made the problems worse if anything.

 

[tiburonfirst]

roly, i don't think it's specific areas.
members with problems that i know for sure are located in ca, tx, fl, va, ny, nh, al .......

 

[JimmyJet]

Sorry if this has already been mentioned, but site performance improved considerably when I switched from Firefox to Opera. My computers run Linux but it might be worth a try for Windows users. Opera is free.

 

[rolygate]

If you use a Mac on an excellent ISP, even away off in another country, the pageload time is under 3 seconds. That's for any page on the site, even if you haven't been there before. It tells us that the servers and hosting are A1. For a large forum, it is an absolutely excellent time, since 5 seconds is acceptable for that profile.

We will certainly try to ease the situation for those with issues, when we can find a solution. Ultimately, a browser or PC or ISP provider change (and often all of them) will make a thousand times more difference than anything we can do. The main areas we could try to help are:
- Finding a good CDN in areas with known ISP network issues
- Finding some way to delay the 'junk' content loading till after the ECF content load, for those with PC issues

We'll keep at it although there are no immediate solutions in sight.
