Voor als iDEAL het niet lijkt te doen kun je meestal de status hier opvragen: [Wayback/Archive] iDEAL Beschikbaarheid Dashboard.

GitLab pages issues today again? (and report on 2023-10-30: Gitlab.com is down (#17054) · Issues · GitLab.com / GitLab Infrastructure Team / production · GitLab)

Posted by jpluimers on 2024/03/12

Still working on handling open Chrome tabs after having moved in the period that GitLab had quite a few issues causing my PagerDuty alerts to go wild.

Today PagerDuty gave me 7 calls in 4 hours again (see [Wayback/Archive] Jeroen Wiert Pluimers @wiert@mastodon.social on X: “@gitlab Since 20240312T1727Z I get PagerDuty alerts from HetrixTools for some pages hosted on GitLab. It would be nice if someone could have a look at gitlab.com/gitlab-com/gl-infra/production/-/issues/17717).

In adddition I need to check if anything made it to the GitLab issue list from the 20230827 connectivity issues I mentioned at [Wayback/Archive] Jeroen Wiert Pluimers @wiert@mastodon.social on X: “Is it @gitlab hosting having transcontinental issues, or are other continental connections affected as well? These are from two different *.gitlab.io pages as measured via @HetrixTools . No issues are listed at status.gitlab.com.

Back then, this was the most important one: [Wayback/Archive] GitLab System Status: GitLab.com availability issues – October 30, 2023 15:39 UTC

Likely because of this, wiert.me.gitlab.io had been down for a while as well on 20231031 (see [Wayback/Archive] wiert.me.gitlab.io (Recent History) – HetrixTools down from 2023-10-30T15:24Z until 2023-10-30T16:14Z for 3 + 3 + 11 + 27 = 44 minutes.)

Back then, the hardest part was to quickly find out if there was indeed an issue being investigated at all.

The GitLab status multi-media account on Twitter just points to the status page, which makes it hard to find the underlying issue.

I didn’t archive that one in time, but when I got the alerts it didn’t show anything and when it was resolved it was already beyond the cut-off timestamp to mark it as “same day” and the graph didn’t show much down-time [Wayback/Archive] GitLab System Status graph didn’t show much down-time:

The Delphi documentation site docwiki.embarcadero.com has been down/up oscillating for 4 days is now down for almost a day.

Posted by jpluimers on 2022/03/08

The [Wayback/Archive] Embarcadero/IDERA Documentation Wiki has been mostly down since March 3rd, 2022 (not the main page, but almost all other pages are).

I modified [Wayback/Archive] Docwiki https – EmbarcaderoMonitoring to show the actual status of a deeper page as the (mostly static) top page is up, so monitoring that is useless as the deeper pages are down.

The deeper pages are dynamic and require a functioning MySQL database connection. That connection is mostly down (the error message is not clear, so this could be a network or a database server problem, or maybe even a loadbalancer gradually entering bit heaven).

Since it had been down for like 6 days in February*, I’d expect Idera to keep an eye on it and prepare for more downtime. Apparently that’s either not a 24×7 thing for them or  they missed the “pre” in preparation as it is dead-silent on .

It also runs on an unsupported version of Mediawiki 1.31** which by itself does not explain the outage, but does indicate that their idea of handling their internal lifetime management is different than what they advocate to clients in their software subscription model, see [Wayback/Archive] Delphi – Embarcadero store, [Wayback/Archive] Update Subscription – Embarcadero and [Wayback/Archive] Special Offers on RAD Studio, Delphi & C++Builder – Embarcadero:

Some uptime monitoring tools that are still free and understand more than http/https

Posted by jpluimers on 2022/01/19

Since uptimerobot has slowly moving free features, part of my family uses it to monitor uptime of their personal stuff, and I don’t want to pay for the free monitoring I do on Embarcadero infrastructure (I know that they have been phasing out older useful sites for ages, but even their main sites were down for 2 days about a year ago).

Yes, I know the competitiveness of [Wayback] Website monitoring – Wikipedia, and I’m glad Uptimerobot has been there for a relatively long time, but alas: for personal use…

The list of of the pricing pages of each site, containing a one line summary blurb if it was available:

Binding #Uptimerobot monitoring to your own subdomain: embarcaderomonitoring.wiert.me

Posted by jpluimers on 2021/01/01

Below a few screenshots on how to bind your own subdomain to a set of uptimerobot monitors.

This case is about [Archive.isembarcaderomonitoring.wiert.me, which I setup because of the not so well way that Embarcadero maintained their web facing infrastructure in the past.

The steps for that are really simple, assuming you already have an uptimerobot account and some monitor set-up. If you don’t: check out the first video (thanks onewebstreet!) linked below the fold, as it is a step-by-step introduction.

Steps for your own subdomain

If you like video more than a list of steps, check out the second video (thanks Kyle!) below the fold.

  1. Ensure you have a DNS CNAME record that points your subdomain (in my case embarcaderomonitoring.wiert.me) to stats.uptimerobot.com:

    Note that [Archive.is] stats.uptimerobot.com by itself will not display any dashboard, as it requires a CNAME to be involved that is registered in the Uptime robot Custom Domain list.

  2. Login to Uptime robot, which brings you to uptimerobot.com/dashboard#mainDashboard
  3. Click on settings, which brings you to uptimerobot.com/dashboard#mySettings
  4. Observe the “Disable RSS” (or “Enable RSS” if you have not yet enabled it) and the “this link” (which in my case points to this RSS feed [WayBack])
  5. Clicking on “show them” will get you something like this:
  6. Clicking on the pencil icon then will get you where you can set the “Custom Domain”, which notes

    Custom Domain

    (make sure you create a CNAME DNS record for your domain to stats.uptimerobot.com. And, it can take up to 30 mins for the custom domain to be activated.)

  7. Wait a while and check your CNAME for a valid Uptime robot status dashboard.
