I use Mailwasher to remotely & automatically clear any spam from my server every 10 mins, but I also filter my PN mail through there too.
The errors have been showing up every hour at 38 minutes past the hour for both my dedicated server and also PN mail indicating that something is happening every hour stopping me from accessing either mail boxes. Other than at 38 mins past the hour everything else seems ok.
I checked here on the forums earlier on today to see if anyone else was seeing something similar, but I didnt see anything, so resolved to look into it further when I had chance to properly do so.
Anyhow the crux is I just noticed the SS report that there are problems with ptw-ag1,
Ive just done a tracert and sure enough.

Aside from the times around 38 mins past the hour, everything else seems ok. Bear in mind it only auto checks every 10 mins so it could also be affecting a few mins either side.
Thought Id mention it... as it may help you track down the fault. Some script running every hour on the half-hour thats crapping out that pipe?

Quote from: Oldjim this is almost certainly relevant
ty OJ, youre likely correct. That post wasnt there when I originally came in to see if I could see anything relevant at about 1pm, which is when I checked all the current posts.
At 4pm after seeing the SS, I thought it may be wise to advise PN, that I wasnt seeing speed issues, just total loss of being able to access the internet.
I thought how the fact it was repeat happening at the same time each hour may be of some relevance for their trouble shooting.
Quote data transfer temporarily broke for the gateway
oops lol.. oh well I'll stay on ptw-gw02. for now
Cheers

Checked the forum and saw this thread and swapped Gateways.
Most inconvenient midway through a Wordpress site upgrade for a new client
SWMBO reports that no *new* expletives were used, but there was an interesting arrangement of some old favourites. Off to check if the upgrade was successful?
