Service Restored

We believe that the stability issues we've been experiencing today have been resolved.

Service Instability Tonight

We're working on a thread leak bug that cropped up after the new SSL connection performance issues were fixed. This results in the web site becoming very slow, and syncing for any device that attempts to make a new connection will also be unreliable. This issue should be resolved before the morning.

New Connection Delay Problem Fixed

Over the past few weeks we've noticed a problem where new SSL connections to the service sometimes took tens of seconds to become established. This issue also affected the web site, since it requires https.
The problem has been identified as a bug in Apache Tomcat's APR connector. A workaround was deployed tonight. The result should be slightly quicker syncing and smooth web site page loads at the busier times of the day.

iPhone 2.2 Firmware Released

Apple released their iPhone/iPod Touch 2.2 firmware update today. We're excited about this because it includes a fix for the 'freezing iPhone' problem that some users have been experiencing. We'd like to hear from users who have updated their devices, particularly users who previously had experienced the freezing syndrome.

Plaxo Back Up

Plaxo have been kind enough to white-list our IP addresses on their high traffic blocker, while we resolve why we're overloading their API. We need to determine what level of traffic is acceptable to Plaxo and dial down our traffic to suit. So Plaxo service is back up at present.

Plaxo Again Not Working

Plaxo sync has been down for several days. Since we've not been able to resolve the issue with Plaxo. They say we're using their API excessively, but after a fair bit of work on our end (we added special rate-limiting code to our service, used packet sniffing and log file data to analyze our API use) we don't see any evidence of excessive traffic. Until we can correlate what Plaxo are seeing with something we have control over on our end that we can fix, unfortunately Plaxo sync will be down.
Google contact sync is working well, and it's not hard to export contacts from Plaxo and import to GMail.

New Data Center

Service is back up, running in our new Silicon Valley colocation facility. The move to the coast gives us access to vastly increased bandwidth, redundant network paths, highly reliable power and plenty of space for expansion. Plaxo service is also currently working, since we have new IP addresses that Plaxo are not currently blocking.

Server Maintenance

We are making some improvements to our network.  The service will be down temporarily while they are completed.  The down time should be brief, and everything is scheduled to be back up shortly.

Plaxo Sync Back Up

We've resolved the problems with Plaxo sync (which related to the high volume of traffic we were sending to their API). Plaxo users should be syncing now.
UPDATE: it's back down again. It looks like we tripped the excessive traffic limit at Plaxo again. We're investigating...

Plaxo Sync Down

Plaxo sync is currently not functioning.  Our servers are unable to communicate with their servers.  We are investigating the cause.  So far we do know that it is not our code and it is not our general Internet connectivity, but we are still looking into what is happening, and what we can do.  Stay tuned.
